Redescriptions and Lectotype Designations of some Exotic Chrysopidae (Neur.)
Authors: Tjeder BO
Published: July 2010

The author has had the opportunity to study some type specimens of species of the genus Chrysopa Leach, I8I5. The species in question were mostly described in a way that does not allow sure identification. Redescriptions have therefore been prepared, when necessary, and lectotypes have been selected in cases when the descriptions were based on more than one single specimen. Some cases of new synonymy have been discovered.
Diurnal Activity in the Dusky Cockroach, Ectobius lapponicus L. (Blattodea)
Authors: Dreisig Hans
Published: July 2010

The activity of the cockroach Ectobius lapponicus was found to differ in males and females in the field, the males being active during the afternoon, the females after sunset. The difference was thought to be due to an inhibition by low temperatures in the males, displacing the activity towards an earlier period of the day. This is in accordance with a theory concerning sensitization, and different thresholds of release dependent on light and temperature as established for the stridulation in Orthoptera Ensifera and the locomotion in a domestic cockroach. A relationship between the amount of activity and the relative humidity was found in the nymphs. Laboratory experiments showed that the activity at constant temperature was released by a change from light to darkness. If low temperatures were applied during the dark period, the activity was displaced to the latter half of the light period. The influence of illumination on the activity was investigated, a faint illumination being more favourable than total darkness.
The Behaviour of Locusta migratoria R.&F. (Salt., Arcidiidae) in Relation to Simple Visual Stimuli at Different Radiation Intensities
Authors: Gärdefors Dag
Published: July 2010

The relation between radiation intensity and visual preferences in Locusta migratoria was tested with four different types of visual stimuli. At high radiation intensity, the strongest preference was for black and at low radiation intensity for vertical lines. The possible ecological significance of the preferences demonstrated is discussed.
Süsswassertardigraden aus Nordeuropa
Authors: Mihelcic Franz
Published: July 2010

The distribution and ecology of Tardigrada in interstitial habitats in northern Europe is discussed. Known results point only to species of the genera Macrobiotus and Hypsibíus (fam. Macrobiotidae) as being psammophilous. Fourteen species were found; of these six belong to the genus Macrobiotus and eight to Hypsibius. Three species from each genus are new. Adaptations of true freshwater Tardigrada are discussed, the major aspect of which is the development of prehensile claws.

S. rufipes Wahlb. is a species related to S. splendens Meig. but distinctly different. The differences are described and the male genitalia figured. The established synonymy S. nubeculosus Zett.=S. cuprarius L. has been confirmed. S. nigripes Zett. is a synonym of S. splendens Meig. (syn. nov.). S. minimus Zett. has been fixed by lectotype designation as a synonym of S. cuprarius L.
The Re-isolation of Neoaplectana bibionis Bovien (Nematodea) from Danish Bibionids (Diptera) and Their Possible Use as Biological Control Agents
Authors: Lindhardt K. , Poinar George O.
Published: July 2010

In. the spring of I97I, Neoaplectana bibionis Bovien was re-isolated from larvae and pupae of Bibio hortulanus L. and other bibionids from 3 localities in Denmark. Third stage infective larvae were recovered and used to initiate laboratory cultures. When nematodes were injected into the mouth of the greater wax moth larvae, Galleria mellonella L., they quickly penetrated into the hemocoel of the living insects and brought about their death. Successive nematode generations also occurred on artificial media used for rearing Neoaplectana carpocapsae Weiser. A specific rod-shaped bacterium was isolated from the intestine of infective stage larvae and probably has the same relationship to the nematode as N. carpocapsae has to its symbiotic bacterium, Achromobacter nematophilus. This nematode may make an excellent candidate for biological control programs involving soil insects.

Drei neue Hydrocyphon-Arten aus dem Mittelmeergebiet (Coleoptera)1
Authors: Nyholm Tord
Published: July 2010

Three new species of the genus Hydrocyphon Redtb. from the Mediterranean area are described, H. vicinans and H. segrex from south-east Turkey (the former also found in Israel), and H. hamiota from southern Spain. The two first-mentioned species belong to the australis-group, which is characterized by the aedoeagus being symmetrically built throughout. H. vicinans is very closely related to the Cyprian species oblongulus Nyh., while H. segrex takes a more isolated position within the group. H. hamiota belongs to those species In which the ventral-piece of aedoeagus is strongly asymmetric with only one medial appendage (prosthema) developed (the pallidicollisgroup), and its nearest relative is H. laeticolor Nyh., which has also merely been found in the south of Spain so far.

Dissections were made throughout the year of the migrant bug Lygaeus equestris (L.). The state of ovary development and fat body size was classified and presence of food in the stomach was noted. Seasonal mating frequence was observed in the field. The findings are discussed with respect to the migratory periods of the bug.
Two Amblystogeniuln Species (Col. Carabidae) Co-Existing on the Subantarctic Possession Island, Crozet Islands
Authors: Davies Lewis
Published: July 2010

Pit-fall trapping in fell-field habitat at about I00 m a.s. on the sub-antarctic Possession Island, Crozet Islands, showed that surface activity in Amblystogenium minimum Luff (Carabidae) fell suddenly to low levels after mating was largely completed in mid-February. In A. pacificum (Putzeys) also a fall in activity occurred at the same time but this species continued limited activity into late autumn. Both species are autumn breeders, with the last named continuing some egg maturation into the winter. A. minimum of smaller body size had ripe oocytes of smaller mean length than the larger A. pacificum which occurred as brown and black coloured adults. Collecting-out of areas of known size when the two species co-existed gave the following density estimates /m2: on stone and gravel ground about 0.7, and on rock pavement of 2.3 of each species. Comparison of pit-fall trapped samples with that of hand collected material suggest that A. minimum showed no differences between the sexes in overall activity, while in A. pacificum males were more active than females. The latter, larger species was more active than the smaller A. minimum. Limited larval material together with the occurrence of teneral adults in low numbers in February-April suggest an unsynchronized larval life lasting a year or more, and unsynchronized emergence in late summer and autumn of adults that do not breed until the following late summer, so that the total life cycle takes two years or more.

Preparation of Alcohol-Preserved Larvae of Culicidae (Diptera) for Scanning Electron Microscopy
Authors: Dahl Christine
Published: July 2010

A method for preparation of alcohol-preserved culicid larvae for Scanning Electron Microscope (SEM) studies is described. It is based on dehydration by ethanol-xylol and fast evaporation of xylol in +8o° C. for ten minutes. For taxonomic studies such as examination of pecten teeth, comb scales and microtrichiae in magnifications up to 6oooX the method is suitable. For studies of receptor structures on hair-tufts and microstructures of the body integument alcohol preserved material is less satisfactory. The microstructure of the comb scales is figured and their function discussed. Differences in the ultrastructure of the abdominal hair-tufts are pointed out.
Field Observations on the Seasonal Occurrence of Lygaeus eguestris (L.) (Het., Lygaeidae) with Special Reference to Food Plant Phenology
Authors: Kugelberg Otto , Solbreck Christer
Published: July 2010

Lygaeus equestris breeds in open areas. It overwinters in the adult stage, and in the autumn and spring it undertakes migratory flights to and from its hibernation sites. It feeds on the generative parts of a variety of plants. During I969 the population trends of L. equestris and of the flower and seed production of its food plants were studied in eight habitats. High numbers of L. equestris always coincided with peaks in flowering or seed production of the food plants. The spring migration was simultaneous with the start of flowering of the earliest food plants. The autumn migration, however, started when food resources still seemed ample. During the summer, nonmigratory (trivial) flights were important for the bug to keep pace with the changes in food availability. In I970 the distribution of food resources was quite different to that in I969, and consequently the invasion of habitats followed a different pattern. Four periods of flight were recognized: (I) postteneral trivial flights, (2) autumn migration, (3) spring migration, and (4) trivial flights of overwintered bugs. Possible causes of the different types of flight are outlined. The dispersal capacities of the bug are regarded as adaptations to the temporariness of its habitats. The implications of the flight movements on the population dynamics of L. equestris are briefly discussed.
A Late-glacial Insect Fauna from Red Moss, Lancashire, England
Authors: Ashworth Allan C.
Published: July 2010

The Red Moss deposits rest in a hollow which began to collect organic sediments I2,ooo years ago. The sediments, moss peat, sandy organic mud and Phragmites peat, yielded abundant wellpreserved insect remains. The species are all living today but many no longer in the British Isles. The fauna of the Late-glacial environment is one of an open and exposed bog but by Post-glacial time this had been superseded by a fauna of shrub and tree-covered wetland. Other changes in faunal composition have been observed which are thought to have been caused by oscillating thermal conditions. A series of colder and warmer episodes has been postulated which may be broadly correlated to the palynologically inferred climatic history of the Late-glacial. A marked faunal change was observed between the Late- and Post-glacial episodes and it is estimated that summer temperatures rose from IO° C to I6° C in a period of 3o to 45o years based on radiocarbon dating. Faunal changes are independent of lithological boundaries, which, because of the largely organic nature of the sediments, are vegetation controlled and this is thought to demonstrate the more positive response of insects to climatic change.
Similarities between the Dufour Gland Secretions of the Ants Camponotus ligniperda (Latr.) and Camponotus herculeanus (L.) (Hym.)
Authors: Löfqvist Jan , Bergström Gunnar
Published: July 2010

The two ant species Camponotus ligniperda ,(Latr.) and Camponotus herculeanus (L.) show very small differences in morphology and general biology. The present work demonstrates that the two species are very similar also with respect to the composition of the volatile secretions emanating from Dufour's gland in worker ants. As in other formicine ant species analysed by us earlier, the main components are straight chain, satured hydrocarbons with II, I3, I5 and I7 carbons atoms. Tridecane is the dominating component. Unsatured, straight chain hydrocarbons and branched chain, saturated hydrocarbons are also present. We have also identified aliphatic alcohols, ketones and acetates as components of the secretion from Dufour's gland, as well as a11-trans-farnesyl acetate and one isomer of farnesene in trace amounts. Of these compounds hexadecyl acetate is the dominating one. The analyses have been carried out by combined gas chromatography and mass spectrometry and by capillary gas chromatography. In both techniques we have been using a precolumn for isolating the volatile compounds.
Östliche Kiefern-Buschhornblattwespe (Gilpinia verticalis Guss.), ein für Schweden neuer Forstschädling

During the year I957 a species of Saw flies new to Sweden, Gilpinia verticalis Guss., appeared in the province of Medelpad in North Sweden. The species had attacked Scotch Pine planted on an area of about 200 acres. After a discussion of the taxonomic position of G. verticalis in relation to genus Diprion Geoffr. (s. lat.), the author reports about the biology. He also gives an account of predators and hymenopterous parasites. Finally he is treating G. verticalis from an economical standpoint.
Seasonal Polymorphism and Developmental Changes in Organs of Flight and Reproduction in Bivoltine Pondskaters (Hem. Gerridae)
Authors: Møller Andersen N.
Published: July 2010

The seasonal changes in the frequency of long-winged individuals and individuals with reduced flight organs in bivoltine populations of Gerris lacustris (L.) and odontogaster Zett. were investigated by means of regular sampling of adults and rearings of nymphs. Both species have a high frequency of short-winged individuals in the first generation. During the late summer and autumn there is an increase in lacustris nymphs moulting into short-winged adults, while nearly all odontogaster become long-winged. The females of the early summer generation have reduced ventral pigmentation and attain reproductive maturity just after their final moult. Their offspring—the partial second generation—together with the nonreproducing adults of the late summer generation constitute the overwintering population. During the teneral development of newly moulted, long-winged adults lasting for one or two weeks there is a nearly fourfold increase in the mean fibre diameter of flight muscles, a significant growth of the thoracic phragmata, and a pigmentation of mesonotum associated with the development of flight ability. The flight muscles are histolysed during the period of reproductive activity in spring. These observations promote a new hypothesis regarding the adaptive significance of alary polymorphism in aquatic Hemiptera.
Neue Beiträge zur Kenntnis der Tenebrioniden-Fauna von Afghanistan (Coleoptera)
Authors: Kaszab Zoltán
Published: July 2010

The author identified the Tenebrionids (Coleoptera) collected in I962 by Dr. K. Lindberg in Afghanistan. The material contained 85 taxa (species and subspecies). Two are new to Afghanistan (Gnathosia jacobsoni, Pisterotarsa gigantea) while 8 species and 4 subspecies are here described for the first time (Gnathosia brincki, Microdera charpentieri, Adesmia jugalis septentrionalis, Lasiostola bendamira, L. linnei, Thriptera dubia, Pachyscelis klapperichi imitata, Pimelia semenovi saroubiana, Platynoscelis subalpestris, P. lindbergi, Dendarus transcaspicus afghanicus and Luprops afghanicus). A new subspecies of Dendarus transcaspicus is described from Transcaspia. The differences between Trachyderma christophi, Thryptera freyi, T. gracillima and T. dubia sp. nov. are clarified and a key to the Afghanistanian species of the subgenus Platynoscelis s. str. is given, establishing changes in the status of Trichomyatis cylindrica, T. rectangularis, T. hirtipennis and T. ovipennis by assigning these species to genus Platynoscelis.
Commentaires sur la terminologie de l'armure génitale chez les Lépidoptères
Authors: Niculescu Eugen V.
Published: July 2010

In this paper, the author critically discusses the terminology concerning the genital armature in Lepidoptera, with particular reference to the works of Diakonoff, Sibatani and Klots (in Tuxen). It is considered that present-day terminology comprises too many terms (about goo) and that great confusion arises, due to the numerous synonymous and homonymous terms and to the adoption of vernacular terms, as well as of terms referring to minor structures. At the end, the author states several principles which ought to be adopted, with a view to supplying order to terminology and to elucidating it.
A Peculiar Kind of Pigment Cell in the Compound Eye of Lepisma saccharina L. (Thysanura)
Authors: Elofsson Rolf
Published: July 2010

The ultrastructure of the primary pigment cells of the compound eye of Lepisma saccharina is described. The cells are four in number. The pigment granules are contained in fingerlike protrusions from the pigment cells. These protrusions project into the enlarged basal lamina surrounding the ommatidial top. The large basal lamina could have given the impression of a cell (called corneagen) in the light microscope.

New Records of Vertagopus sarekensis (Wahlgren, I906) from Northern Scandinavia (Collembola, Isotomidae)
Authors: Fjellberg Arne
Published: July 2010

Vertagopus sarekensis (Wahlgren) was found on dry localities in alpine region in Northern Norway and Swedish Lappland, where it ascends to the highest mountain tops (2000 m a.s.l.). It is separated from V. westerlundi (Reuter), besides in colour, by morphological details of antenna, number of ventral setae of thorax and abdomen, shape of mucro and general clothing. Adults in reproductive phase show a distinct sexual dimorphism: Abdominal macrochaetae of the male are much shorter and thicker than in the female, and setae of the characteristically swollen frons are thick and thorn-like. A lectotype of V. sarekensis is designated.
Morphology of the Male Genitalia of Lepidoptera I. Ditrysia
Authors: Birket-Smith S.J.R.
Published: July 2010

From the literature on onthogenesis it is concluded, that male genitalia with two pairs of appendices must be considered primitive. The male genitalia of a number of species from three families (Cossidae, Saturniidae, Brahmaeidae) in which the male genitalia comprise two pair of appendices, valvae and valvellae, were dissected. The results are compared to earlier studies of species of Lithosiinae (Arctidae). It is concluded, that morphologically must be distinguished between two types of intromittant organ, or phallos, viz. aedoeagus and pseudaedoeagus.

Gamasina Mites (Acari, Parasitiformes) from Nests of the Mole Talpa europaea L
Authors: Lundqvist Lars
Published: July 2010

From Southern Sweden 2040 gamasina mites of 31 species were collected from 51 nests of Talpa europaea L. The taxicoenosis may be described as a Haemogamasinae—Euryparasitus emarginatus— Myonyssus rossicus acarocoenosis, dominated by Haemogamasus hirsutus. In most species more females than males were found and more adults than larvae and nymphs. In two species, Euryparasitus emarginatus and Parasitus niveus these ratios were different, e.g. ∼ 1.
Laboratory Studies on the Feeding Preference and Feeding Behaviour in Lygaeus equestris (L.) (Het. Lygaeidae)1
Authors: Kugelberg Otto
Published: July 2010

The seed-feeding bug Lygaeus equestris changes and extends its food plant spectrum during its life-cycle. Whether this is the result of only the natural succession of the food plants, or also includes a change in the insect's food preference during its life, was the primary question of the present paper. Feeding-choice tests using ripe seeds from important food plants in the laboratory showed that Cynanchum vincetoxicum seeds were preferred during all stages of life. Among the lesser preferred seeds tested, a shift in preference occurred during the bug's development. It seems probable that this shift may be due as much to the physical as to the chemical properties of the seeds. It is suggested that most of the other plant species exploited for feeding by L. equestris probably serve mainly as substitute food when suitable developmental stages of C. vincetoxicum are absent or in short supply. Furthermore the paper gives some notes on duration of feeding upon seeds and effects of seed coat at initiation of feeding on Cynanchum and Helianthus seeds. During the third larval instar, the preference switches from the endosperm to the seed coat for initiation of feeding on Cynanchum seeds, and so it remains during the following stages. On Helianthus seeds, only adult L. equestris feed as willingly through the coat as directly from the endosperm.

Revision of the North European Species of Cosmetopus Becker (Dipt. Scatophagidae)
Authors: Andersson Hugo
Published: July 2010

Lectotypes are designated for Cordylura dentimana Zetterstedt, 1838, Cordylura fulvipes Zetterstedt, 1838, Cosmetopus bergrothi Becker, 1900, and Cosmetopus simplicipes Becker, 1900. C. fulvipes Zett. is found to be a synonym of C. dentimana Zett. (n. syn.). The opinion that C. bergrothi is a synonym of Cosmetopus longus (Walker, 1849) and that C. simplicipes Beck. should be treated in a separate genus, Pleurochaetella Vockeroth, is confirmed. Cosmetopus ringdahli n. sp. is described and figured on material from Sweden and Finland. Distinctive characters of the other species are discussed and partly figured.
Observations on the Luminescence of the Larval Glowworm, Lampyris noctiluca L. (Col. Lampyridae)
Authors: Dreisig Hans
Published: July 2010

The larval luminescence in L. noctiluca consists in a glow lasting for several seconds (average 7.3 sec.) emitted at irregular intervals while the animal is crawling about during the active period at night. In the adult female the glow is continuous often for several hours. Also some larvae in the last instar were able to glow continuously for hours. Onset of activity in the larvae occurred at a lower critical ambient illumination (6.85 log lux +10) than in adult females (10.10 log lux+10). The dispersion of onsets was greater in larvae than in females. The duration of luminescent activity in the field was ca. 5 hours and at experimental conditions ca. 8 hours. In thc field larvae were mostly seen during late summer, probably because of the low critical illumination, which was also the reason why activity was suspended on moonlit nights. The intensity of moonlight around full moon was ca. 8.00—9.00 log lux+10. In the discussion the following subjects are treated: The function of larval luminescence; the reaction of larvae to ambient illumination; and the difference between glowing and flashing.
Abundance of Tundra Arthropods in Spitsbergen
Authors: Bengtson Sven-Axel , Fjellberg Arne , Solhöy Torstein
Published: July 2010

The late summer abundance of higher taxonomic units of arthropods on different types of coastal tundra in Spitsbergen (approx. 79°N, 12°E) was assessed by means of suction sampling of vegetation and litter and soil samples. Acari and Collembola comprised 96—99 % of the total number of arthropods and some Araneae and Diptera and a few Hymenoptera were regularly recorded. The total abundance (ind./m2) varied between 42—63,000 on lichen covered tundra, 268,000 on wet moss tundra, and 518,000 on grassland. There were considerable similarities in the abundance of major groups of arthropods between the Spitsbergen tundra and high alpine grounds in southern Norway, although in the former area some groups were absent.
The Concept of Oligophagy and the Natural Habitats and Host Plants of Papilio machaon L. in Fennoscandia
Authors: Wiklund Christer
Published: July 2010

In this paper a hypothesis is advanced according to which oligophagous insects have adopted two distinct strategies of habitat/host plant utilization, (1) a "monophagic strategy" being favoured in predictable habitats, making it possible to maximize reproductive success on one host plant per habitat only, (2) a "polyphagic strategy" being compulsively adopted in unpredictable habitats where two or more host plants per habitat have to be utilized for the maintenance of the species. For a partial preliminary test of this hypothesis the natural habitats and host plants of Papilio niachaon in Fennoscandia were investigated. The results indicate that (1) the predictable formations of inland wet-lands and coastal foreshores are the most important habitats (2) Peucedanum palustre, Angelica silvestris, Angelica archangelica ssp. littoralis and norvegica are the dominant host plants and (3) P. machaon appears to have adopted a "monophagic strategy" of habitat/host plant utilization in the predictable habitat categories.

Chromosome Numbers and Notes on Testicular Morphology of some Lebanese Rhopalocera (Insecta: Lepidoptera)
Authors: Larsen Torben B.
Published: July 2010

The chromosome numbers of 54 Lebanese Rhopalocera are given. 11 of them represent species not previously studied, while 26 of the remainder are endemic subspecies (often very characteristic) of species studied elsewhere. The findings are compared to the existing body of knowledge. The karyology is found to be very stable over wide geographical areas and, therefore, chromosome counts are a useful taxonomical tool for many groups of Rhopalocera. The chromosome counts of species not previously studied generally fall within the expected range for the respective genera and families. A simplified technique for karyological studies through non-permanent squash preparations is outlined.

The Gyrinidae of the Bismarck Archipelago and the Solomon Islands (Coleoptera: Gyrinidae)
Authors: Brinck Per
Published: July 2010

Three species of whirligig beetles occur in the Bismarck archipelago (Gyrinus sericeolimbatus Rég., Macrogyrus ovatus Ochs, and Dineutus neobritannicus Ochs). Nine species occur on the Solomon Islands, viz. G. sericeolimbatus Rég., D. heterandrus Ochs and the following species of Dineutus (Callistodineutus): bougainvilleanus Ochs, bufo n.sp., choiseulicola n.sp., cristobalensis n.sp., dispar Ochs, dispersus n.sp., and pagdeni Ochs. - The morphological spectrum of subgenus Callistodineutus is reviewed and the distribution pattern and the differentiation of the species analysed. Ten species (of 11) are endemic. The general character is Indonesian. The Callistodineutus have spread twice over the islands, resulting in an older eastern group and a younger western. The western species are associated with a former continuous land connection, severed about 10 000 years ago. A stage of secondary dispersal (exchange of species among the islands) is still in progress.
Review of genus-group taxa included in the genus Tychius Germar (Coleoptera: Curculionidae)
Authors: Clark Wayne E.
Published: July 2010

Review of world genus-group taxa heretofore assigned to Tychiinae indicates that the subfamily should be delimited to include the genera Apeltarius Desbrochers, Dichotychius Bedel, Itychus Kissinger, Mecynopyga Pierce, Paragoges LeConte, Sibinia Germar, Tychius Germar, Xenotychius Reitter, and their subgenera and synonyms. The status and relationships of formally recognized genus-group taxa within the genus Tychius are reviewed. Henonia Pic and Miccotrogus Schönherr are newly placed in sonynymy with Tychius; Lepidotychius Penecke is considered a subgenus of Tychius. All known host plants of species of Tychius are members of the legume subfamily Papilionoideae. Species from South America and Australia described as Tychius were not correctly assigned and belong in other tychiine genera or in other subfamilies.

Revision of the notescens-group of the genus Micropsectra Kieffer, 1909 (Diptera: Chironomidae)
Authors: Wedal Lars Sä
Published: July 2010

The Palearctic species in the notescens-group of the genus Micropsectra Kieffer are revised. Six species are redescribed and three new species, Micropsectra lindebergi, M. montana and M. nepalensis are described. Lectotypes are designated for 19 species and a neotype is designated for M. insignilobus Kieffer. The females and pupae are included as far as they are known. - Morphologically some of the species are very similar. In one case the only morphological difference between two species is found in the females. An analysis, presented in graphs and tables, is given to make it possible to separate the males of M. insignilobus and M. lindebergi, two morphologically very similar species. Most of the species which are difficult to separate on morphological grounds have a marked difference in their ecology, thus making an identification possible. - Notes on the distribution and ecology of the species are given. - Keys to the males and pupae of the species in the notescens-group are presented.

Post-embryonic development of Lithobius forficatus (L.), (Chilopoda: Lithobiidae)
Authors: Andersson Göran
Published: July 2010

The larval stadia of L. forficatus are easily distinguished by the number of legs and are separated from all other Scandinavian species in having more than 2+2 teeth on the forcipular coxosternite. The variation during development in size, number of coxal pores, ocelli, antennal articles, teeth on forcipular coxosternite, spinulation, projections on tergites 9, 11 and 13, accessory apical claw on the 15 th pair of legs and genitalia are described. Also the difference between male and female and correlation with size within each stadium are given. The number of coxal pores is the best feature for separating the post-larval stadia of L. forficatus. There are probably 9 post-larval stadia in Sweden. The larva media (sensu Verhoeff) is an accidental stadium and only occasionally included in development.
