Fake heads and sexual behaviour in a hairstreak butterfly, Callophrys xami (Lepidoptera: Lycaenidae)Original article
Eur. J. Entomol. 118: 394-398, 2021 | DOI: ten.14411/eje.2021.040 
In several collywobbles, the posterior end of the hindwings resembles a butterfly head when the butterfly is perched with its wings airtight. At that place is bear witness that this "false head" (FH) deflects predator attacks towards non-vital parts of the trunk. If the FH protects from visually oriented predators, its status in an individual butterfly could provide data about its quality to prospective mates. Nosotros tested two hypotheses based on this idea past comparing the probability of mating, duration of copulation and size of the ejaculate received by females of Callophrys xami (Lycaenidae) with an intact FH and those with an ablated FH in a paired...

Eur. J. Entomol. 118: 364-367, 2021 | DOI: 10.14411/eje.2021.038
The cynipoid wasp Gronotoma micromorpha (Perkins) (Hymenoptera: Figitidae) is a parasitoid of the leafage miner Liriomyza trifolii (Burgess) (Diptera: Agromyzidae). The effects of developed age and body size on egg maturation in K. micromorpha were determined. The results showed that its egg load (number of mature eggs per female) increased when offered honey, water, but not hosts for three or six days after developed emergence. However, in that location was no significant difference in the egg loads of 3- and 6-day-former wasps. These findings and the results of previous studies on other cynipoid parasitoids propose that when hosts are not bachelor, females...

Automated pheromone dispensers disrupt the mating behaviour of pest moths past releasing pheromone during their daily activity period, which is not the aforementioned for all target species. These periods usually occur in or shut to night time and last just a few hours, then automated sampling devices are needed to characterize them. However, the commercially bachelor automated models do not provide enough temporal resolution for characterizing the short diel periods of sex of moths. Thus, nosotros congenital and tested a relatively cheap and simple high-temporal-resolution image-sensor insect trap. Information technology consisted of a Raspberry Pi computer with an infrared camera...

Immature individuals of Afrotridactylus cf. usambaricus (Sj�stedt, 1910) were recorded on a marine sandy embankment probably feeding on bacteria, microalgae and mesopsammic organisms. The larvae of this pygmy mole cricket probably obtain these organisms past manipulating grains of sand with their buccal apparatus during the excavation of tunnels close to the surface of the sand. This occurs in daytime during the ebb tide while direct migration to the ocean is in progress. Therefore, the migration occurs according to a diurnal-tidal rhythm having been detected only in correspondence with the low diurnal tides. This rhythmic activity remains in...

Eur. J. Entomol. 118: 123-134, 2021 | DOI: 10.14411/eje.2021.013
The functions of the larval salivary glands (SGs) of Drosophila are traditionally associated with the production of a massive secretion during puparium formation; it is exocytosed into a centrally located lumen and afterwards expectorated via ducts, the throat and oral fissure. This so-called proteinaceous mucilage serves every bit an adhesive to attach the puparial instance to a solid substrate. Great attention has been paid to the secretory cells of SGs, which are famous for their giant polytene chromosomes. However, essentially less attending has been devoted to individual or common ducts that form the well-nigh proximal portion of the SG organ via which the glue...

Eur. J. Entomol. 118: 111-122, 2021 | DOI: 10.14411/eje.2021.012
In bush-crickets, males produce a calling song to announce their presence to females. Females ready to mate respond either by a phonotactic approach or signal their presence acoustically by establishing a kind of duet. This duetting behaviour is typical of phaneropterid bush-crickets, of which many species in Europe are flightless. In the long-winged genus Phaneroptera, the females likewise answer acoustically to the male person calling song, which is quite similar in the three westward European species in this genus. After acoustical contact, however, the behaviour of males and females of the 3 species differ markedly. In P. nana, males and females...

Eur. J. Entomol. 118: 57-62, 2021 | DOI: 10.14411/eje.2021.007
The distance from southern Italy to Denmark is well-nigh the same as the length of Finland from south to northward. A study of the biogeography of insects, such as ants, would accept a lot of attempt and funding to sample the whole expanse. Hither, a citizen science approach is used to obtain distribution records for mound-building Formica ants in Finland. This resulted in samples from ii,434 ant nests, of which two,363 were for nests of the target species group. The data obtained helps define the northern limits of the species in Finland and resulted in three new records for F. suecica Adlerz, 1902, which is a cherry-red-listed species in Finland. In addition,...
Influence of the eggs of Ephestia kuehniella (Lepidoptera: Pyralidae) reared on different diets on the performance of the predatory bug Orius laevigatus (Hemiptera: Anthocoridae)Original commodity

Eur. J. Entomol. 118: 51-56, 2021 | DOI: 10.14411/eje.2021.006
The predatory bug, Orius laevigatus (Fieber, 1860) (Hemiptera: Anthocoridae), is an important biological control amanuensis and widely used for augmentative biological control of the western bloom thrips, Frankliniella occidentalis Pergande, 1895 (Thysanoptera: Thripidae) in greenhouse crops. This bug is generally reared using the Mediterranean flour moth, Ephestia kuehniella Zeller, 1879 (Lepidoptera: Pyralidae). The aim of this report was to determine the effects of E. kuehniella eggs produced past adult moths reared on unlike larval diets on the performance of O. laevigatus. The diets were 95% cornmeal + five% yeast (CY...
Temperature differences associated with colour do not decide where the acorn pismire Temnothorax crassispinus (Hymenoptera: Formicidae) chooses to nestOriginal article

Temperature is an important factor for invertebrates. Social insects build nests, which forth with their ability to thermoregulate, provide shelter from extreme temperatures. Nonetheless, for many species of ants the most mutual method of decision-making the temperature inside a nest is to choose a suitable nest site. During a field experiment, the option of nest site past the acorn ant Temnothorax crassispinus, a species which lives in coniferous and mixed forests, was studied. Information technology typically occupies ephemeral nest sites and tin can move to a new nest site several times in 1 flavour. Information technology was predicted that in early on spring, night coloured nest sites would exist...
Ecological niche modelling of species of the rose gall wasp Diplolepis (Hymenoptera: Cynipidae) on the Iberian PeninsulaOriginal commodity

Eur. J. Entomol. 118: 31-45, 2021 | DOI: 10.14411/eje.2021.004
Diplolepis (Hymenoptera: Cynipidae) are gall wasps that induce conspicuous galls on Rosa spp. (Rosaceae). These species are distributed globally and in Europe some are especially common and are founder organisms of biological communities equanimous of different insects. However, the ecological niches of these species have not been studied in detail. Nosotros modelled the potential distributions of these species using the locations of the galls of the iv most abundant species of Diplolepis on the Iberian Peninsula (Diplolepis mayri, Diplolepis rosae, Diplolepis eglanteriae and Diplolepis nervosa, the galls...
Invasive chocolate-brown marmorated stink bug (Hemiptera: Pentatomidae) facilitates feeding of European wasps and ants (Hymenoptera: Vespidae, Formicidae) on constitute exudatesOriginal article
Davide SCACCINI, Alberto POZZEBON
Eur. J. Entomol. 118: 24-30, 2021 | DOI: 10.14411/eje.2021.003
The brown marmorated stink bug, Halyomorpha halys, is a polyphagous species from eastern Asia, which has spread to America and Europe where it damages many crops. In recently colonized areas, facilitative interactions between H. halys and native insects are poorly investigated. In this study, we study for the first time facilitation of native wasp and ant feeding by H. halys in Europe. The facilitation was related to the outflow of plant exudates caused by H. halys feeding on manna ash trees, where they have aggregated in response to an aggregation pheromone, which then attracted species of Hymenoptera to the infested trees....
The associations between footing protrude (Coleoptera: Carabidae) communities and environmental condition in floodplain forests in the Pannonian BasinOriginal article

Eur. J. Entomol. 118: 14-23, 2021 | DOI: 10.14411/eje.2021.002
Nosotros studied assemblages of carabids in viii similar habitats, five in Slovakia and three in Serbia. The footing beetles were caught by pitfall traps from February 2015 until November 2016. We compared the incidence of Carabidae in floodplain forests and ecotones alongside the River Danube in Slovakia and the Rivers Tisza and Begej in Serbia. We determined their association with anthropogenic effects,diversity of plants in the unlike vegetation layers, cover of vegetation layers (herbaceous plants, shrubs and copse), area of forest stands, circumference of woods stands, altitude to forest edge, age of forest stands, depth of leaf litter and physico-chemical...
Insect photoperiodism: B�nning'south hypothesis, the history and development of an ideaReview
David SAUNDERS
Eur. J. Entomol. 118: ane-13, 2021 | DOI: 10.14411/eje.2021.001
In insects, the photoperiodic system comprises a linked sequence of events from photoreception to final seasonally-appropriate phenotypes such as overwintering diapause. The starting time and terminal of these events are reasonably well known, but central phenomena such as those distinguishing brusk from long days (fourth dimension measurement) and the nature, accumulation and transfer of this information through evolution, metamorphosis and sometimes beyond generations remains obscure. B�nning's intuitive suggestion that photoperiodic time measurement was a role of the cyclic system, made 8 decades ago, still, has provided a framework for numerous studies...
