the ornate skink , cyclodina ornata , is a rare species of skink endemic to new zealand .

this species was once widespread through much of the north island and on many offshore islands in the hauraki gulf and north of the coromandel peninsula .

habitat destruction and predation by introduced species has now reduced their range to scattered localities throughout the north island as far south as wellington , as well as on the three kings islands , great barrier island , and a few other offshore islands .

ornate skinks co-exist widely with copper skinks , and at selected localities with robust skinks , mokohinau skinks , mcgregor 's skinks , poor knights skinks and on great barrier and little barrier islands , marbled skinks .

ornate skinks are not currently known to co-exist with whitaker 's skinks .

ornate skinks can be identified by the white or yellowish " teardrop " edged with black , below each eye .

although the new zealand skink fauna is known to be highly diverse , a substantial proportion of the recognised species remain undescribed . we completed a taxonomic revision of the ornate skink ( oligosoma ornatum ( gray , 1843 ) ) as a previous molecular study indicated that it represented a species complex . as part of this work we have resolved some nomenclatural issues involving this species and a similar species , o . aeneum ( girard , 1857 ) . a new skink species , oligosoma roimata sp . nov . , is described from the poor knights islands , off the northeast coast of the north island of new zealand . this species is diagnosed by a range of morphological characters and genetic differentiation from o . ornatum . the conservation status of the new taxon appears to be of concern as it is endemic to the poor knights islands and has rarely been seen over the past two decades .

mainland sanctuaries , where introduced mammalian predators are controlled or excluded , have the potential to improve the conservation status of new zealand lizards . this is due to the reliance of a large number of species on habitats unavailable on offshore islands . however , despite considerable predator control efforts , lizard populations are still in decline , even in some mainland sanctuaries . the main cause of this failure appears to be that predator control is hard to sustain and largely targeted at protecting bird populations , which require lower levels of predator suppression than lizard populations . even fenced , mainland , predator - exclusion sites are prone to reinvasions , particularly of mice , which are difficult to exclude at the outset . episodic irruptions of mice within fenced sanctuaries , and other mammalian predator species in unfenced sanctuaries , can quickly decrease lizard numbers . small lizard populations are particularly vulnerable . we discuss two case studies to illustrate population dynamics and limitations to understanding mechanisms underlying patterns of population declines in new zealand skinks : ornate skinks ( oligosoma ornatum ) in a fenced mainland site and speckled skinks ( o . infrapunctatum ) in an unfenced mainland site . we also speculate about the effects on lizards of native and non - native birds and introduced social insects , including wasps and ants . understanding biological interactions and obtaining more species - and situation - specific data for lizards will provide information on limits to recovery , detection time frames after management actions , risks and benefits of habitat enhancements and density targets for introduced species where total eradication is impractical .

new zealand has a very diverse group of geckos and skinks . the distribution and habits of many are poorly known , and additional species are still being discovered , and others are being established through genetic studies . geckos are distinguished from skinks by having either velvet - like or bumpy skin and a fixed gaze ( they cannot blink ) . skinks are sleek and shiny with scales that shed one at a time and that shine in the sun .
( green ) geckos are diurnal and tend to be tree - dwelling , and favour shrubland and forest habitats but have been found in tussock grasslands of otago and are known to occur in plantation forests .
geckos ( usually darker colours such as brown ) are nocturnal , and favour rocky outcrops , gullies with rock or log cover and sometimes forest .
geckos to the untrained eye . some individuals have a bight mustard - yellow crescent on the nape of the neck , and often also with blotches of the same colour along body and tail .
geckos can be brightly coloured and have a distinctive orange / yellow mouth lining . they have slender toes and tend to be arboreal and primarily nocturnal .
geckos are slender and elegant animals with distinctive stripes . they are strictly arboreal in habit and nocturnal .
is the single species in the tukutuku genus and this species is only found on stewart island where it is most commonly located in sub alpine scrub .
oligosoma skinks are both diurnal and nocturnal and and occur in diverse habitats from rocky and sandy shorelines , to forests , to subalpine habitats . nocturnal species tend to live in damp , thickly vegetated , lowland areas in northern new zealand .
lizards are critical for ecosystem processes ; they pollinate native plants and disperse native plant seeds through eating fruit .
predation by introduced mammals ( e . g . cats , rats , mustelids ) is the biggest threat posed to new zealand lizards , and lizards can become exceptionally abundant in the absence of mammalian predation . loss and / or fragmentation of habitat through development , habitat degradation by introduced browsing mammals ( e . g . pigs , livestock , deer , goats , possums ) , removal of logs and rocks , and excessive collecting also contribute to on - going declines of lizards over all parts of new zealand .
maintain wide and interconnected zones of potential lizard habitat , e . g . indigenous forest and shrubland , rocky gullies , cliffs and other distinctive habitat types .
raise awareness of staff and contractors of the presence of lizards and the need to protect them .
take photographs or write a detailed description when lizards are found . this can be used for later identification .

horntail or wood wasp is the common name for any of the 150 non-social species of the family siricidae , of the order hymenoptera , a type of xylophagous sawfly .

this family was formerly believed to be the sole living representative of the superfamily siricoidea , a group well represented in paleogene and mesozoic times , but the family anaxyelidae has been linked to this group .

there are ten living genera placed in the family , and an additional three genera described from fossils .

the last tergite of the abdomen has a strong , projecting spike , thus giving the group its common name ( the ovipositor is typically longer and also projects posteriorly , but it is not the source of the name ) .

a typical adult horntail is brown , blue , or black with yellow parts , and may often reach up to 4 cm ( 1.6 in ) long .

the pigeon horntail ( tremex columba ) can grow up to 5 cm ( 2.0 in ) long ( not counting the ovipositor ) , among the longest of all hymenoptera .

female horntails lay their eggs in trees .

the larvae bore into the wood and live in the tree for up to two years , possibly more .

they typically migrate to just under the bark before pupation .

the spiral groove on the ovipositor is visible on the photograph but not easily to the naked eye .

horntail

horntail also appears in zero ' s early game ( after alpha and beta meet ) but only shows the giant left head . horntail starts crying after being attacked by zero , and freud states that horntail is just a baby .
the pigeon tremex is a type of non - stinging wasp , known as a horntail .

. if one gives the wizard a sword he will kill the horntail and give the player a key .
time limit shows the total time allowed to fight but you must spawn the full horntail within 15 minutes .
scientists have discovered that , in the case of other species of horntail wasps , fungal associates can attract these parasites . ibalia is attracted to volatile chemicals released by the fungus in its early stages of development ahead of the horntail larva’s feeding tunnel . ichneumon wasps are drawn to fungal chemicals excreted in the horntail grub’s feces .
horntail wasps look like they can deliver a wicked sting , but that stout syringe is actually for laying eggs .
the hungarian horntail was part of the dragon challenge roller coaster in the wizarding world of harry potter along with the chinese fireball .
there is , however , reason to suspect the relationship has a dark side . the fungus may play a role in attracting parasitic wasps that reduce the horntail larvae’s numbers . a larva tunneling inside a tree would seem to be safe from enemies , but there are other wasps that have evolved to seek out horntail grubs . female giant ichneumon wasps in the genus megarhyssa have long , whip - like ovipositors that drill deep to attach an egg to a horntail grub . wasps in the ibaliidae family reach young horntail larvae at a more shallow depth . ichneumon larvae feed externally on nearly mature horntail larvae . ibaliid larvae feed internally initially , externally later .
supposedly the most dangerous of all dragon breeds , the hungarian horntail has black scales and is lizard - like in appearance .
when faced with the agony of trying to ask someone to the yule ball , harry said that he would have preferred facing the horntail again .
what made you want to look up horntail ? please tell us where you read or heard it ( including the quote , if possible ) .
since the beginning , it was intended to bring the horntail to life mostly through computer animation . the task was assigned to industrial light & magic , whose digital effects artists fashioned a horntail model starting from the maquette provided by dudman’s team . the digital model was used for the remainder of the forest sequence , as well as the entire first task scene . a small - scale version of the horntail also appears in the selection scene .
the hungarian horntail appears in the attraction at the wizarding world of harry potter . riders encounter the dragon when harry potter and ronald weasley fly muggles to the quidditch pitch . riders enter a real set of the wooden bridge where they encounter a animatronic hungarian horntail , which breathes false fire at them .
oh , don’t worry about ’em , harry , they’re seriously misunderstood creatures… although , i have to admit that horntail is a right nasty piece of work .
how do they get inside ? horntail females lay eggs in dead , dying , or fallen logs . if a property owner’s home is built using lumber infested with horntail larvae , the adult insects may emerge in homes after completion of their life cycle . adults will chew through plaster or sheet rock walls to get to living spaces .
horntail wasps do not bite or sting . also , they cannot infest lumber after it has been cut so there is no risk of additional generations of horntails in the studs or household furniture . most horntail wasps will emerge within the first year of construction , though a few may linger and emerge as long as 2 or 3 years after construction .
the horntail ' s appearance in the movie is based off of the dragons in the movie ,
reign of fire
( 2002 ) . the appearance of the horntail in movie adaptations is more akin to that of a traditional wyvern ; as it has no forelegs , a true classical dragon having forelegs , hindlegs and wings like described in the books .
horntail is a boss that , much like gollux , consists of multiple body parts that appear in different maps . the party must defeat all of them to win the boss battle .
horntail is an evil power - hungry dragon who rebelled against the nine spirits ' rule and distorted the area with evil in order to kidnap an egg of nine spirit dragon and consolidate its power over minar forest . horntail now holds an ambitious wish of ruling over the entire minar forest . it now waits for powerful maplers to enter the cave of life to challenge it .

the horntail is featured in the video game version of harry potter and the deathly hallows : part 1 and lives in the dark caves , a wizarding world forestal area with a giant cave .
when the player approaches the cave , he / she sees moira trapped in a cage ; she pleads with the player to slay horntail , giving the pendant to enter the cave and do so .
oh , don ' t worry about ' em , harry , they ' re seriously misunderstood creatures — although , i have to admit that horntail is a right nasty piece of work .

designing the hungarian horntail for the film adaptation of goblet of fire proved to be an arduous challenge : given the long tradition of dragon depictions in both films and general media , the creature designers focused on what not to do in order to distinguish the horntail ( as well as the other first task dragons ) from previous dragon designs . the creature effects team set out to portray a spectacular and surprising creature .
the adult female can be seen searching the same areas used by the pigeon tremex , although they tend to be present a bit later in the summer . developing horntail larvae can be detected under the bark by the female and she subsequently drills into the wood to the tunnel of the horntail larva . during egg laying ( oviposition ) the host larva is paralyzed with a sting after which the egg is laid . the parasitic wasp larva feeds on the paralyzed horntail larva , consuming it completely within a couple of weeks . it then pupates and remains dormant under the bark until the following summer , when the adults emerge .
horntails get their name from the projection on the back of their abdomen , which often is confused for a stinger . some people refer to these insects as wood wasps , as horntail larvae bore into wood .

for years , biologists couldn ' t understand how the horntail drill worked . unlike traditional drills , which require additional force ( think of a construction worker bearing down on a jackhammer ) , the horntail can drill from any angle with little effort and little body weight . after years of studying the tiny insects , scientists finally figured out that the two needles inch their way into wood , pushing off and reinforcing each other like a zipper .
the hungarian horntail is a dragon native to hungary and is considered to be one of the most dangerous dragon breeds , if not the most dangerous . [ 1 ] it possesses black scales and is lizard - like in appearance .
this party quest is located in the cave of life in the leafre canyons . it leads up to the fight with one of the most powerful boss monsters in the game , horntail . to enter , one must be in a party of 1 - 6 , and be over the level of 130 . the leader also must have completed the secret medicine of transformation certificate of squad badge quest , which will give the certificate to enter the horntail ' s cave .
horntail wasps emerging into houses through plaster board ( sheetrock ) come from larvae living in the studs behind the plaster board . studs that were cut from infested logs can contain horntail larvae that survived the processing . the larvae survived , in part , because the studs were not kiln dried or were inadequately dried . the adult wasps chewing their way out of infested studs also chew through almost any building material used to cover the wood ( plaster board or paneling ) .
a photograph found in the monster park shows horntail with spiegelmann , suggesting the two are friends , or used to be . ( if it is shown to spieglemann , he ' ll bribe the player into keeping quiet about it . )
colliding into a bridge , the horntail falls into an uncertain fate , whereas its miniature counterpart makes a cameo in harry potter and the half - blood prince — roasting chestnuts on a cart outside weasley wizard wheezes . jim mitchell was satisfied with the final results of the horntail animation and rendering for goblet of fire , saying that “ilm did a great job with the animation and look of the bat - like dragon making it as real as any dragon i’ve seen . ”
a hungarian horntail was to be faced during the first task of the 1994 triwizard tournament , in an effort to retrieve a golden egg . [ 2 ] harry potter had to face it after selecting , at random , a tiny model depicting the horntail from a bag . he summoned his firebolt broomstick to him and used it to manoeuvre around the dragon to retrieve the egg . it is stated that ron weasley ' s brother charlie helped transport the dragon from romania . [ 2 ]
in most cases , it will not be necessary to do anything to control horntails . the adult horntail does not reinfest seasoned wood . it will not lay eggs in wood that is inside the home . damaged wood can often be repaired or replaced .
in the film adaptation of harry potter and the goblet of fire , the horntail broke free of its chain and attacked harry . the two of them fought in an exciting chase that spanned all around the castle grounds , almost causing harry to fall to his death at one point when he was trying to reach his firebolt , but when the chase continued , harry flew through the viaduct , which the horntail crashed into , breaking its wing and causing it to fall into the chasm below , presumably to its death .
based on the approved design , kate hill sculpted two quarter - scale horntail maquettes , which were moulded in fiberglass and painted for reference . a larger scanning model was then devised and supplied to industrial light & magic to create the digital model of the dragon .
the pottermore illustration of the hungarian horntail resembles its description in the novels , having four legs and two wings , with a lizard - like head and being black in colour with bronze spikes and claws . this is markedly different than the depiction of the dragon in the film .
in the film adaptation of harry potter and the half - blood prince , the hungarian horntail model that was given to harry from barty crouch snr is seen in the roast chestnuts sale , located in diagon alley . it is possible that harry gave his dragon to fred and george who put it there .
and there was the horntail , at the other end of the enclosure , crouched low over her clutch of eggs , her wings half - furled , her evil , yellow eyes upon him , a monstrous , scaly , black lizard , thrashing her spiked tail , heaving yard - long gouge marks in the hard ground .
though the horntail ( or wood wasp ) looks like a wasp , it is not a wasp at all . it does not have a stinger , nor does it have venom . the long projection at the rear of its abdomen is an ovipositor ( egg depositor ) . this is only seen in the female . on the top side of the abdomen , at its tip , is a triangular “horn” ( best seen in a side view ) . this is what gives the horntail its name . they are about one inch long with a cylindrical body . they are brown , black or metalic blue in color with yellow or red markings .
don ' t be scared of the two giant , whip - like needles on the end of a horntail wasp . they ' re not stingers ; they ' re drill bits . horntails use these needles ( which can be longer than their entire bodies ! ) to drill into trees , where they deposit their young .
after fighting the preliminary heads , the party will be directed to the map for the real fight . to start the bossfight , destroy the pink crystal on the far right of the map to summon horntail . players must stand clear away from the middle when this happens , otherwise they ' d most likely end up dying .
two large and bizarre looking insects are commonly associated with dying branches and trunks of several commonly grown hardwood trees . one of these is an insect that develops as a borer within the tree—the pigeon tremex horntail ( tremex columba ) . the other is the most common natural enemy of this insect , the giant ichneumon wasp ( megarhyssa macrurus ) .
it has black scales , and is lizard - like in appearance . it also has yellow eyes , with vertical pupils like a cat ' s , bronze horns and similarly coloured spikes that protrude from its long tail which it will gladly deploy in combat . the dragon ' s roar is a yowling , screeching scream , and its flame can reach to about fifty feet . while having a very far reaching flame the horntail ' s breath can reach extremely high temperatures as it made a stone turn red hot in seconds . its eggs are cement - coloured and particularly hard - shelled . the horntail ' s foods of choice include cattle , sheep , goats , and whenever possible , humans .
the maquettes also served as reference for a full - scale horntail animatronic built by nick dudman’s special effects team . the puppet would be used in the early shots that revealed the creature , which show it in a distance . dudman recalled : “the production wanted a lightweight life - size dragon head to run about on set with . once we had that head and eight feet of the neck , we suggested that we could sculpt the rest very quickly , keeping it very basic . we used that for wide shots of the dragon in its cage . ” kate hill led the creation of the full - size sculpture of the horntail — aided by waldo mason , andy hunt and other sculptors .
despite the warning colors , horntail wasps are generally non - aggressive and ( one source says ) harmless . both genders of horntail wasp species have short spines at the tip of their abdomen , but females appear to have two menacing stingers . the thicker , longer one is actually an ovipositor . the ovipositor is a tube used by the female to directly inject eggs into tree trunks and other durable wood where they are less likely to found and eaten by other insects . that sturdy spine aids in splitting the wood before the eggs are laid . larvae hatch inside the wood and tunnel through it , emerging as adults . despite the great efforts to use deep wood to protect the horntail larvae , they are eaten by the larvae of other parasitic wasps that have also hatched in the same tree . those that survive emerge from the tree in adult form . if the tree has been harvested and used for building material before then , it is not unusual to see these adults inside as they come out of wood . adults drink nectar and water .
the wasp and fungus are mutually supportive . the fungus benefits by hitching a ride to new host trees , where it can spread and ultimately produce fruiting bodies - shelf mushrooms known as mossy maze polypore . the wasp depends on the fungus to complete its life cycle . without cerrena unicolor to provide food and soften wood , pigeon horntail larvae do not survive .
an unusual pest problem of large wasps chewing holes through plaster board and emerging within recently constructed homes came to our attention in the summer of 1991 . these 1 and 1 / 4 inch long , black or dark blue wasps have been identified as horntails or horntail wasps . the name comes from the spearlike projection on the tail end of both male and female horntails .
a pigeon horntail that survives the perils of youth eventually becomes a pupa , the “resting stage” in which it transforms into an adult . adult horntails chew their way out of their host trees between june and october in the northeast u . s . males emerge before females , gathering in loose swarms over treetops . females look for these “bachelor” parties and select suitable mates .
the pigeon tremex is a type of non - stinging wasp , known as a horntail ( hymenoptera : siricidae ) . they are large insects , with a tubular shaped body and generally brown color , marked with yellow . females , which are considerably larger than males , have a stout spine projecting from the hind end . this is the ovipositor , used to insert eggs under bark .
no one could fault you for running away , screaming in terror , if you saw a large , flying , cigar - shaped insect armed with a “stinger” bigger than a sewing needle . thankfully , the female pigeon horntail wood wasp is harmless . that spear on its rear isn’t meant to pierce skin . it’s for drilling into wood ; and it lays the foundation – literally – for a remarkable inter - species relationship .
in the film adaptation of harry potter and the goblet of fire , the horntail ' s manner of breathing fire by shooting a pair of chemical liquids that cause a fire blast on contact is possibly based on the same fire - breathing manner used by dragons in the movie reign of fire ( 2002 ) . [ 1 ] this was further followed by other media such as game of thrones series and gods of egypt ( 2016 ) .
adults in the forest , horntails can complete the entire life cycle in a year or two . if the wood has been dried and made into lumber , the horntail life cycle can take as long as five years . when the adult comes out of the cocoon , it chews its way out of the wood . the adult makes a round hole in the surface of the wood . the exit holes are usually about 1 / 4″ in diameter .
vincent described how the parasitoid wasp species megarhyssa macrurus , is able to use her egg laying tube to drill down into tree bark , where she deposits her eggs onto the larvae of the pidgeon tremaz horntail ( how did this come up as a topic ? ! over dessert ? ) . this is possible thanks to a complex structure of three tubes that can bend and flex as the wasp drills , allowing her to position her eggs with pinpoint precision .
the finished animatronic was mounted on a mobile , wheeled unit — which eased transport of the enormous prop . the head could perform a wide range of motion , including an articulated neck and mouth , and movable eyes , eyelids and nostrils . the wings could make limited movements and the body could move from side to side . the puppet was shot inside a hydraulically - operated breakaway cage . in addition , the full - size horntail was also used at the film’s world premiere in london .
the map below showcases ( in red ) the states and territories of north america where the horntail wasp may be found ( but is not limited to ) . this sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species ' given lifespan . some species are naturally confined by environment , weather , mating habits , food resources and the like while others see widespread expansion across most , or all , of north america .
in the novel , the first task ends in the arena ; in the film , however , the sequence was taken into a more action - oriented direction : the horntail breaks from its restraints , chasing harry outside the arena . visual effects supervisor jim mitchell developed the idea . he related : “there never was any of the chase around hogwarts castle , but one day when i was checking out the huge physical model of the castle for some establishing shots , i thought how cool would it be see harry and the dragon flying through its deep ravines , under bridges and past these giant , stoned structures . i imagined the dragon landing on one of the steep towers and roaring like king kong on the empire state building . mike newell and the producers liked the idea and so the sequence grew to include the chase . i think it opened the sequence up and made it more perilous and exciting than it originally was . ” the chase scene offered the opportunity to further showcase horntail animation — swooping like a hawk or crawling like a bat on the hogwarts towers .
rowling’s description in the novel made mention of “clawed front legs , ” a trait that was initially considered , but discarded ; in order to maintain artistic integrity , the filmmakers eventually steered towards a four - limbed configuration of the anatomy , harkening back to norbert from the first film . the key trait of the creature — the ‘horntail’ — was initially envisioned as a scorpion’s stinger , or a tail tip with clusters or rows of spikes . in the end , a large spear - like tail tip covered in smaller spikes was chosen . as the design process progressed , it was decided to make horns the key visual motif of the monster — endowing it with a crown of horns on its head , which continued mane - like down its neck , back and tail , ending in the spiked tip . some of the horns on the creature’s head can also flare out and hinge back to highlight its emotional state . the final design — penned by paul catling — was also strongly influenced by birds of prey : a hawk - like beaked tip of the mouth and a proportionally large chest housing powerful flight muscles completed the imposing look of the hungarian horntail .
a fertile female pigeon horntail seeks a tree that is dead , dying , or weakened . maple and beech are preferred hosts , but elm , apple , poplar , oaks , and other hardwoods are also targets . once she selects a tree , she begins drilling in the manner described above . foresters call the wasps “stump stabbers” in reference to this behavior . she lays two to seven eggs at a time at a depth of about three - fourths of an inch . she then extracts her ovipositor and repeats the process , elsewhere on the same tree , and / or in other trees .
the eggs of the raspberry horntail , a wood wasp , are pearly white and oblong , with a curved point at one end . mature larvae are white and cylindrical , with dark heads and a short spine on the tail end . they have three pairs of legs , no prolegs , and attain a length of up to 1 inch ( 2 . 5 cm ) . the adult wasps , which are seldom seen , vary from 0 . 5 to 0 . 75 inch ( 12–18 mm ) in length . the females are marked with bright yellow and black ; the males are mostly black .
horntails are attracted to dying , burned or recently cut wood . the female deposits her eggs into the wood of host trees , most commonly silver maple , ash , cottonwood , and elm . along with the eggs , she deposits a fungus that will continue to degrade the already compromised wood . the eggs hatch in 3 - 4 weeks and the larvae begin consuming the fungus along with the wood . this may last anywhere from one to five years depending on the climate . the adult horntail chews through the last bit of wood and emerges , leaving a round exit hole 1 / 4″ to 1 / 2″ in diameter .
at the same time she lays her eggs , she deposits the spores of a wood - rotting fungus , cerrena unicolor . these spores are stored in two mucus - filled pouches near the base of her ovipositor . as the fungus grows in the tree , it secretes enzymes that break down cellulose . this partly digested wood is consumed by the horntail larvae ; female larvae store the fungal strands in pockets that will become the mucus pouches in the adult wasps . as the larvae grow , they bore tunnels through sapwood and heartwood , fifteen centimeters to two meters or more in length , curving towards the exterior surface of the tree .
the giant ichneumon wasp is a parasitic wasp ( hymenoptera : ichneumonidae ) specific to the pigeon tremex . it also is generally brown in color with yellow and orange markings . it has a very elongated body form and most notably long ‘tails’ that may extend a couple of inches . these ‘tails’ also are the ovipositor and supporting structures , used to insert eggs into wood onto developing pigeon tremex horntail laravae . altogether the body and ovipositor of this insect may extend more than 5 inches . ( males are smaller , lack the ovipositor , and have a blunt tip of the abdomen . ) despite its rather fearsome appearance , the giant ichneumon wasp is harmless to humans and can not sting .
horntails are also known for being one of the most vicious and aggressive breeds of dragon and that is saying something since all dragons are known to be ferocious ; even rubeus hagrid commented on their ferocity saying that the horntail was a ' right nasty piece of work ' . [ 3 ] this breed is especially aggressive when protecting their young . along with their viciousness , tail spikes and fiery breath , horntails are shown being extremely fast in flight while able to keep up with a firebolt broomstick , a broom capable of going from 0 to 150 miles per hour in 10 seconds . horntails are also seen able to keep up with harry potter ' s flying skills ; a very impressive feat considering harry ' s talent as a seeker . [ 2 ]
animatronic systems supervisor matt denton mounted the creature’s head to a computer - controlled performance system that was devised cannibalizing parts of aragog and the basilisk built for the second film , in order to save both time and budget . the skull of the dragon was fabricated in fireproof fiberlass with a steel beak , epoxy teeth and silicone skin . for a dragon that could actually breathe fire , the mouth interior was lined with flame retardant nomex . the entire head was coated inside and out with flamebar , a flexible fire - resistant elastomeric silicone sealant . john richardson and his mechanical effects team fitted the mouth with twin flame jets using a benturi system that blasted liquid propane over a pilot flame . the horntail animatronic could shoot a 36 - foot stream of dragonfire at the camera .
development of the horntail’s body language was assigned to animation director steve rollins , who collaborated with visual effects supervisor jim mitchell . much like the design itself , the animation mainly referenced birds of prey — such as eagles and owls . “when you see the movie , look for the head twitching , head cocked , and quick twitchy movements ; these were all from the bird references , ” said visual effects supervisor tim alexander . other minor references included reptiles and bats . different iterations of the animation sequences were attempted before a final version was selected by the director . “where the dragon crawls across the rocks , we’d do one version with it using its hind legs , another where it’s crouched down , using the batlike hands on its wings to crawl , ” alexander explained .
horntail as a whole consists of his three heads , two arms , wings , legs , and tail . in the main fight , his left head and right head retain some of the abilities from the preliminary battled , while the middle head uses fire - based attacks and skills , as well as summon wyverns . the left and right heads have 100 , 000 , 000 hp in easy mode , 330 , 000 , 000 hp each on normal mode and 3 , 300 , 000 , 000 hp in chaos mode . the middle head has 235 , 200 , 000 hp in easy mode , 490 , 000 , 000 hp in normal mode and 3 , 900 , 000 , 000 hp in chaos mode . all three heads can cast weapon cancel and magic cancel . in chaos mode , the left head can cast physical reflect , and the right head can cast magical reflect .
adults of the pigeon tremex are active from june through early october . females may be seen crawling over the bark and occasionally may insert their ovipositor into the trunk . ( dead females are sometimes seen stuck on the trunk with their ovipositor embedded in the tree . ) if the conditions under the bark are suitable , notably a sufficiently low moisture content , a few eggs ( 2 to 7 ) will be laid into the wood . along with the eggs , the white rot fungus daedalea unicolor is also introduced . this fungus grows within the wood ahead of the horntail larvae and is required for their successful development . infection of trees with white rot fungus accelerates decay and further weakens the structure of affected trees . larvae typically take nearly a year to become full - grown and then pupate just under the bark . the adult emerges in about a month after pupation and cuts a circular exit hole from which it leaves the tree .
crafting the dragonfire was another challenge . “fire is a natural occurrence , everyone knows what it looks like . they know if it looks fake , ” alexander said . “we needed fire to be directable , and that took a long time . ” many of the dragonfire shots were a combination of the digital horntail and practical fire elements provided by john richardson’s team — who built a handheld flamethrower device that blasted flames across rocks in the first task arena set . for the chase scene , the fire was portrayed with composited practical flame elements shot by physical effects supervisor geoff heron , as well as digital fire simulations created in ilm’s zeno pipeline . said system made use of stanford university’s ‘physbam’ physics simulations . “stanford’s smoke simulations created roiling and spinning particles , ” said alexander . “it was similar to the live - action pyro elements , so we used that as the basis for our cg fire . smoke tends to move slower than fire , so we did a lot of work with speed and scale — too fast , and it spurted everywhere ; too slow , and it didn’t create the roiling effect . we then developed a shader look with very sharp detail broken up at the ridges . ”
wasps may be the bane of many a summer picnic but they are now the inspiration behind a new type of flexible medical probe . the biomimetic instrument is being developed by a team at the department of mechanical engineering , imperial college london , uk . its design is based on the ovipositor ( egg - laying tube ) of a female wood wasp .
the wood wasp’s ovipositor looks like two hollow needles , one inside the other , each of which is lined with backward - facing teeth to give purchase as the wasp ‘drills’ progressively into the bark of a tree . this takes surprisingly little force , making it attractive for carrying out minimally invasive procedures such as brain biopsies without having to exploit a natural orifice .
unlike the wood wasp’s ovipositor , however , the probe ‘displaces’ the tissue rather than removing it . the current prototype consists of four interlocking probe segments lined with 50μ teeth and propelled by small motors and actuators . the ultimate aim is to be able to steer the probe in three dimensions through soft tissue and monitor its progress .
dr ferdinando rodriguez , at imperial , explains that existing percutaneous instruments can be divided into two main groups – thick and non - flexible probes ( bioposy probe and laparoscopes ) and thin and flexible needles ( such as a brachytherapy needle ) .
he says , ‘thick and non - flexible probes can be pointed to the target with the aid of a visualisation system and will not deform under load , but their manipulation causes significant pressure on the tissue , limiting the surgeon’s degrees of freedom .
‘conversely , thin and flexible probes tend to be less damaging to the surrounding tissue , but deflect and buckle against tissue resistance , resulting in placement accuracy which is inversely proportional to the depth of the target’ .
furthermore , the ‘underlying technological and functional limitation’ of both devices is that they cannot be guided along curvilinear trajectories . this ‘limits their application to surgical procedures where a straight - line approach is viable’ .
a ‘scaled up’ prototype of the team’s flexible probe , measuring 12mm - wide and about 30cm long , has been demonstrated but a final prototype will be no more than a few millimetres in diameter .
‘developing a multi - part probe of a few millimetres outer diameter will mean identifying materials , manufacturing methods and surface treatments that will work at this scale , ’ remarks rodriguez . ‘particularly challenging will be [ ensuring ] that the probe can sustain the loading conditions incurred during actuation , while being sufficiently flexible not to damage surrounding tissue during insertion . ’
the team is exploring medical - grade silicon , latex rubber and possibly even polytetrafluoroethylene ( ptfe ) from which to manufacture their device .
professor tony anson , of uk biomedical materials research company diameter ltd , says , ‘there’s a significant global market for such a device , as there are many patients with problematic physiology who would benefit here . ’
he agrees , though , that finding a suitable material will be challenging . he says , ‘i would discount latex , as there have been too many problems with latex gloves . medical - grade silicon could work but it has a possible demerit because of its high surface friction , and ptfe is a good biomaterial , although in some cases it lacks the right mechanical properties – both have potential .
‘i notice that polyurethane ( pu ) isn’t mentioned . i think pu shows promise , but then so could some combination of materials , coatings or polymer composites , ’ he says . anson suggests that the manufacturing technology may ultimately influence the choice of material .
the prototype of a few millimetres should be available before the end of 2015 for clinical trials to take place . rodriguez says , ‘the feasibility study focused on probe design , actuation and control . it also laid the foundation for an “intelligent probe , ” where the insertion process is guided interactively by pre - operative image data , allowing deep lesions of the brain and other regions of the human body to be accessed with greater accuracy and repeatability’ .

before the main battle , the party must fight the right head and left head in two preliminary battles . both have 100 , 000 , 000 hp in easy mode , 330 , 000 , 000 hp each on normal mode and 3 , 300 , 000 , 000 hp in chaos mode . the left head has ice - based attacks , can summon red wyverns , blue wyverns ( not in easy mode ) , and dark wyvern ( 2 at a time ) , can create spiked tombstones on the floor ( below the platform ) and cast weapon cancel and magic cancel . the right head is similar , but uses electric attacks .
his right arm and left arm can dispel and seduce and drain mp . both have 90 , 800 , 000 hp in easy mode , 230 , 000 , 000 hp in normal mode and 2 , 300 , 000 , 000 hp in chaos mode .
his wings can heal both the hp and mp of the rest of the body and can summon green cornians and dark cornians . they have 100 , 000 , 000 hp in easy mode , 270 , 000 , 000 hp in normal and 2 , 700 , 000 , 000 hp in chaos .
his legs have an earthquake stomp attack with a powerful knockback that can also stun . it has 67 , 200 , 000 hp in easy mode , 130 , 000 , 000 hp in normal and 1 , 300 , 000 , 000 hp in chaos .
his tail also has an earthquake attack and can summon a poison mist cloud . it has 33 , 600 , 000 hp in easy mode , 80 , 000 , 000 hp in normal and 900 , 000 , 000 hp in chaos . ( it is recommended that players destroy this part first ; aside from the poison its touch attack can do upwards of 27 , 000 points of damage , or 33 , 000 when buffed . )
his body is not dangerous unless physically touched , but only when all parts are reduced to zero hp is he finally defeated .
in chaos mode , the background turns from being a cave to a stormy , dark background . this is also seen in the battle against chaos pink bean and pre - revamped chaos zakum . this is probably because the black mage corrupted them , making them stronger and more menacing .

improperly dried lumber from infested logs is most at risk for problems with these pests . firewood stored inside can also contain horntails .
exit holes in tree trunks – adult horntails that emerge in the living space of a home can cause a disturbance . the exit holes can be unsightly , especially in wood that has been painted or stained .
structural damage concerns horntails are actually wasps , but these insects do not bite or sting . they rarely cause structural damage since they do not lay their eggs in construction wood after it is cut and dry . but , if infested wood was used in a home without proper drying and aging , adults might show up as they emerge from the infested wood .
horntails will not infest furniture or re - infest wood inside a home . still , they are a nuisance to people and may cause alarm to homeowners who think their house is being destroyed by a wood damaging insect .
prevention nevertheless , homeowners can help prevent infestation by storing firewood outside the home . firewood should only be brought in when it will be used .
if infestation is suspected , homeowners are encouraged to request an inspection by an orkin specialist to ensure any evidence of wood damage is not from authentic wood damaging insects able to cause structural problems .
eggs female horntails deposit their eggs into the trunks of trees . most species choose coniferous , softwood trees , but a few species choose broadleaf , hardwood trees . chosen trees are usually in decline from disease or attack from other insects .
larvae when the eggs hatch , the larvae burrow into the wood . they pack tunnels with droppings and wood shavings as they burrow . when the larvae are mature , they burrow close to the surface of the wood and make a silken cocoon inside the tunnel , where they then change into adults .

the giant ichneumon wasp is the most common natural enemy of the pigeon tremex .
pigeon tremex are not considered serious pests since attacks are limited to trees and limbs that are in serious decline or very recently dead .
the pigeon tremex develops as a wood borer and the larvae are cylindrical - bodied , cream colored grubs that live within the wood . however , they are not considered serious pests since attacks are limited to trees or individual limbs that are in serious decline or very recently dead .
only certain hardwood trees are attacked by pigeon tremex , notably silver maple , ash , cottonwood , and elm . ( several other species of horntails also occur in the state but these are limited to conifers , usually those growing in forested areas . ) however , the insect may become locally abundant as these host trees become increasingly susceptible due to old age or disease . because pigeon tremex is not considered to be a primary pest , controls have not been developed , although it likely can be temporarily managed by use of insecticides in a manner similar to that of other wood borers . ( see colorado state university extension fact sheet 5 . 530 , shade tree borers . )
( the ovipositor of the female consists of three filaments . the central part is the actual ovipositor , capable of drilling through wood . although appearing as a single filament , it is actually made of two parts , that interlock , slide against each other , and are tipped with the cutting edge . although very thin , it is a tube and the egg moves down the minute channel in its center during egg laying . the ovipositor is normally sheathed within two other thin filament structures that are protective in function , do not assist with drilling and bow out prominently around the insect during egg laying . )
