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 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 .

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 .

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 .

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’ .

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 . )
