The paper describes the method and algorithm for creating maps of hydrolandscapes to solve practical tasks of predicting and controlling the abundance of common bloodsucking insects, such as horseflies and mosquitoes. The hydrolandscape method consists in dividing the regions into zones based on the source, distribution, and storage of moisture as the most important ecosystemic component. The method evaluates the influence of insufficient or excessive moisture content on the activity of amphibiotic insects. Hydrolandscapes unite the landscapes that are similar in moisture content, relief, mesoclimate, soils, vegetation, and groups of bloodsucking insects. In this paper, we describe the experience of applying this method to different regions of Northwestern Russia: Novgorod, Leningrad, Pskov provinces and the Komi Republic. The hydrolandscape method provides the means for predicting the species composition and relative abundance of bloodsucking insects in remote areas before their economic development.

This paper is an analytical review of the current state of population biology research of the European corn borer Ostrinia nubilalis Hbn. and its closest congeners. It focuses on the specific features of adult reproductive behavior that are formalized as evolutionary stable strategies and alternative reproductive tactics ensuring effective use of environmental resources by the populations within the species' distribution range. The strategies and tactics are considered both at the level of the effects of environmental factors contributing to their implementation and at the level of the results of their implementation. Specific examples are discussed that show the importance of studying these strategies and tactics for pest control. The available material also reveals the importance of studying the Ostrinia spp. population biology for elaboration of their taxonomy. In particular, the European populations of O. scapulalis and O. nubilalis demonstrate a complicated system of reproductive relations, with persistent barriers of sexual isolation formed in some cases and panmixis maintained in others; in this way, the integral biological system retains its high adaptive potential within the range. As a result, the insects varying within a wide range of morphological, genetic, behavioral, and ecological properties form an integral population system of O. nubilalis sensu lato, a complicated taxonomic continuum within which O. nubilalis sensu stricto and O. scapulalis can be distinguished as semispecies.

Species of argid sawflies of the small genus Pseudarge Gussakovskij, 1935 have been known for a long time only based on females. The paper gives for the first time illustrated descriptions of the males of two Middle Asian species, Pseudargerubicunda Gussakovskij, 1935 and Ps. ushinskii Gussakovskij, 1935, and also provides characters from the description of the male of Pseudargeeversmanni Gussakovskij, 1935 made by V.M. Ermolenko, which was overlooked by the authors of the genus revision. Photographs are given for these three species (including the habitus of the primary types and genital structures of both sexes), as well as an amended identification key. The intraspecific variation and differentiating characters of the species of this genus are discussed. [ABSTRACT FROM AUTHOR]

This paper presents the results of long-term research of the biodiversity and quantitative invasion indices of feather mites associated with passerines in the Lower Don area. Between 2001 and 2019, we examined 2246 passerine specimens belonging to 85 species, 47 genera, and 23 families and comprising the majority of passerine species in the region. A total of 86 feather mite species belonging to 15 genera, 7 families, and 2 superfamilies (Analgoidea and Pterolichoidea) were found on 83 species of passerine hosts. A detailed taxonomic analysis of the parasite fauna has been carried out. Four species of feather mites are recorded here for the first time for the Russian fauna: Proctophyllodes balati Černý, 1978, P.remizicola Černý, 1979, P.cetti Badek, Mironov et Dabert, 2008 (Proctophyllodidae), and Corydolichus calandrellicolus Mironov et Sayakova, 2001 (Ochrolichidae). The faunistic complexes of feather mites of all the studied passerine families and their specific features in the study region have been analyzed. Parasitological indices of invasion (intensity and prevalence) for each feather mite species on each avian host have been estimated by statistical processing of the long-term quantitative data.

Ixodid tick communities in Primorskii Territory are characterized by significant species diversity. The species richness of Ixodidae is higher on the Primorye islands than on the mainland. Bi- and polydominant pasture ixodid communities occur only on islands. Of the eight islands surveyed in 1982–1983, only Putyatin Island had a monodominant tick community with predominance of Haemaphysalis concinna Koch, 1844. This paper is focused on the current structure of adult ixodid hemipopulations on Putyatin Island. Ticks were collected from vegetation by flagging on May 17–21, 2021 at different sites of the island. The following species were recorded (in descending order of abundance): Dermacentor silvarum Olenev, 1932, Haemaphysalis concinna Koch, 1844, Ixodes persulcatus Schulze, 1930, H.japonica douglasi Nuttall et Warburton, 1915, and I.pavlovskyipavlovskyi Pomerantzev, 1946. In total, 354 ixodid ticks were collected, and their low abundance was observed. According to the data of 2021, H.longicornis Neumann, 1901 was no longer found on Putyatin Island, I.pavlovskyi was recorded for the first time, the abundance of D.silvarum increased significantly, and that of I.persulcatus increased to a lesser extent. The possible causes of changes in the structure of ixodid tick communities are discussed. Putyatin Island currently has a bidominant complex of ixodid ticks, with 45.8% of D.silvarum and 33.3% of H.concinna. [ABSTRACT FROM AUTHOR]

The distribution and host-parasite relationships of fleas of the genus Xenopsylla (Pulicidae) and their significance as plague vectors are analyzed. The worldwide distribution of plague foci and the role of this flea genus in pathogen circulation in various regions are considered. Xenopsylla fleas either act as the only main vectors or are included in the main vector pool in 114 out of 255 known natural plague foci around the world. Spontaneous infection with the plague microbe has been detected for 21 species of this genus, and 17 species are considered the main plague vectors in some foci. The flea X. cheopis is the most significant plague vector in Africa and South-East Asia. [ABSTRACT FROM AUTHOR]

The flea Monopsyllus sciurorum sciurorum (Schrank, 1803), a parasite of the red squirrel Sciurus vulgaris (L., 1758), is distributed throughout Europe and Western Siberia and can be found on 70 species of hosts. Its parasitism on minks constitutes a major problem for fur farming in some European countries. We have analyzed the host species composition and the conditions of parasitism of M. s. sciurorum on minks at the Savvatyevo fur farm in Tver Province of Russia. [ABSTRACT FROM AUTHOR]

Resistance to insecticides is one of the main parameters determining the effectiveness of a biocontrol agent because it allows the combination of biological and chemical control. The predatory bug Orius laevigatus is widely used for biological control of various insect pests in greenhouses. Its natural geographic range includes Western, Central, and Southern Europe, the Mediterranean, Northern Africa, and Southern Asia. Orius laevigatus was recently found in Stavropol Territory of Russia, although it is not clear whether the Stavropol population originated from some natural population or from the individuals that had escaped from local greenhouses. To estimate the biocontrol potential of the Stavropol population, we have compared its resistance to Actara® (a neonicotinoid insecticide often applied in greenhouses) with that of the individuals currently used in Russia for biological control of greenhouse pests (the biocontrol population). The experiments showed that the compared populations did not differ in their resistance to Actara®: the observed differences between the relative decreases in 24 h survival, total lifespan, female fecundity, and egg hatching rate were not statistically significant. However, individual variability in the Stavropol population was lower than that in the biocontrol population. In combination, these data suggest that the Stavropol population quite recently originated from the individuals that had escaped from local greenhouses; therefore, it cannot be considered a particularly promising source for further selection for insecticide resistance.

ecies of sawflies of the genus Dolerus Panzer (Hymenoptera: Tenthredinidae) are found in the agricultural landscape of the North-West of Russia. The sawflies of this genus tend to have a highly uneven distribution in the agricultural landscape. Sawflies of the genus Dolerus have their highest species diversity in the agrocenoses of perennial grasses (timothy grass + clover), at field margins and forest edges. [ABSTRACT FROM AUTHOR]

The taxonomic problems associated with the validity of the subgeneric names in the genus Omocestus I. Bolívar, 1878 are discussed. The subgeneric names Haplomocestus Tarbinsky, 1940 and Dreuxius Defaut, 1988 proposed after 1930 are unavailable, according to Articles 13.1 and 13.3 of the International Code of Zoological Nomenclature (ICZN, 1999). Here the genus is divided into three subgenera, namely Omocestus s. str. [type species Omocestus viridulus (Linnaeus, 1758), by subsequent designation (Kirby, 1910)], Dirshius Harz, 1975, stat. resurr. [type species Omocestus haemorrhoidalis (Charpentier, 1825), by original designation], and Tarbinskius subgen. n. [type species Omocestus bolivari Chopard, 1939, designated here]. A brief diagnosis and the species composition are given for each subgenus. [ABSTRACT FROM AUTHOR]

The efficacy of two predatory phytoseiid mite species, Phytoseiulus persimilis and Transeius montdorensis, against the spider mite Tetranychus urticae on rose plants of Kordana variety was evaluated in the laboratory. All variants of the experiment were carried out in triplicate over 14 days, at a temperature of +25°C and relative air humidity of 70–75%. At the end of the experiment with Ph. persimilis, the density of T. urticae decreased from 20.8 ± 0.9 to 0.9 ± 0.5 ind. per model leaf; the biological efficacy of the predator was 95.7%. In the variant with T. montdorensis, the density of T. urticae decreased from 20.1 ± 1.0 to 8.7 ± 1.1 ind. per leaf, and the biological efficacy did not exceed 63.0%. In the variant without predatory mites, the density of T. urticae increased by the end of the experiment from 22.4 ± 1.0 to 65.6 ± 1.5 ind. per leaf. A single release of Ph. persimilis at a predator : prey ratio of 1 : 10 was effective, but a single release of T. montdorensis failed to produce the expected result. Therefore, the latter species can only be used as an additional predator when other entomoacariphages are present in the greenhouse. [ABSTRACT FROM AUTHOR]

Four species are recorded from Russia for the first time: Altica cirsicola Ohno, 1960, Neocrepidodera recticollis (Jacoby, 1885), Sphaeroderma tarsatum Baly, 1874, and Cassida koreana Borowiec & Cho, 2011. A new color form of Cryptocephalus flavoscutellaris Medvedev, 1973 is described from Sakhalin. The variability of body coloration in Cryptocephalus nigrofasciatus Jacoby, 1885 is discussed. The following synonymy is confirmed: Cryptocephalus nigrofasciatus Jacoby, 1885 = Cryptocephalus turpis Chen, 1942. Two taxa, Cryptocephalus sagamensis Tomov, 1982 from South Korea and C.nigrofasciatus, are probably conspecific.

Photos of the adult habitus and genitalia are provided for all the above species and their close allies. [ABSTRACT FROM AUTHOR]

The lacewing Chrysoperla nigrocapitata Henry, Brooks, Johnson, Haruyama, Duelli et Mochizuki, 2015 (Neuroptera, Chrysopidae) was first recorded in Russia in 2021. This paper provides information on the biology, trophic associations, phenology, and habitats of the species in the south of Primorskii Territory. Late-instar larvae of Ch.nigrocapitata were observed feeding on young nymphs of the leaf-footed bugs Coreus marginatus orientalis (Kiritshenko, 1916) and Molipteryx fuliginosa (Uhler, 1860) (Heteroptera, Coreidae) with weakly sclerotized cuticle, as well as on fruit sap of the red raspberry Rubus idaeus L. (Rosaceae). The development of the species from egg to adult was observed under laboratory conditions. The developmental time of the pupae ranged from 11 to 7 days (m = 9.5 ± 0.56 days) at the mean daily air temperature varying from 18.7 to 27.8°C (m = 23.2 ± 1.21°C; n = 6). [ABSTRACT FROM AUTHOR]

The paper reports the first results of studying mosquitoes (Diptera: Culicidae) in different biotopes of the Subpolar Urals within the Yugyd-Va National Park territory. Field collections were carried out on July 12–15, 2021. As a result, 11 species were found: Aedes communis (De Geer, 1776), A.diantaeus Howard, Dyar et Knab, 1913, A.hexodontus Dyar, 1916, A.euedes Howard, Dyar et Knab, 1913, A.excrucians (Walker, 1856), A.intrudens Dyar, 1919, A.nigripes (Zetterstedt, 1838), A.pullatus (Coquillett, 1904), A.punctor (Kirby, 1837), Culiseta alaskaensis (Ludlow, 1906), and C.bergrothi (Edwards, 1921). Mosquitoes were trophically active round the clock during the polar day. The activity of mosquito attacks depended on the air temperature (Spearman correlation coefficient R = 0.5 at p = 0.005). The tundra species Aedes hexodontus Dyar, 1916 preferred lichen mountain tundra areas. [ABSTRACT FROM AUTHOR]

The effect of sporal and mycelial VOCs of entomopathogenic fungi of the genus Lecanicillium on primary behavioral responses of the predatory bug Orius laevigatus was studied in laboratory experiments. Free choice of adult Orius bugs between the sporulating mycelium and the nutrient medium without the fungus was evaluated in Petri dishes (24 h, in the presence of S. cerealella eggs and a bean leaf) and in 2-chamber olfactometers (1 h, without food). Repellent response in the bugs was caused by the mycelium of three strains: Lecanicillium lecanii strain Vl 29, L. dimorphum strain ARSEF 2332, and L. attenuatum strain Vit 71, with the index of aggregation IA ranging from −40.7 to −50 (P < 0.05). A significant attractive response with an IA value of +43.3 was caused by L. lecanii strain Vl 5. The response of O. laevigatus to VOCs of Lecanicillium fungi after 1 h in 2-chamber olfactometers was predominantly neutral, with pronounced repellency observed only for L. lecanii strain Vl 29 (IA = −72) and L. dimorphum strain ARSEF 8057 (IA = −36.8).

In the subfamily Tryphoninae, the genus Aderaeon Townes et Townes, 1949, stat. resurr. (with five species) and the tribe Exenterini, stat. resurr. (with 15 genera and about 250 species), are resurrected. These taxa were recently synonymized with the genus Erromenus and the tribe Tryphonini, respectively, in the fundamental cladistic revision of the Tryphoninae genera (Bennet, 2015). Both taxa show a high level of morphological isolation and have autapomorphies well separating them not only from other tryphonines, but also from all other Ichneumonidae. Cladistic analysis ignoring such important morphological novelties that constitute high-rank autapomorphies, as well as specific evolutionary trends including the formation of novel morphological types of egg and ovipositor in these groups, would lead to unjustified destruction of the existing system. A new monotypic subgenus Praectenochirasubgen. n. is described in the genus Ctenochira Foerster, 1855 (tribe Tryphonini). The subgenus is established for a morphologically extremely primitive species, C.orientalis Kasparyan, 1993, whose placement in Ctenochira is defined by the presence of areas with sensilla on the ventral side of the flagellomeres, a wide ovipositor sheath, and a sting-like ovipositor typical of this genus; yet three other synapomorphies defining the genus Ctenochira, namely the polished bulge at the mandible base, the transverse depression behind the middle of the second metasomal tergite, and the characteristic dorsal notch at the ovipositor sheath apex, are absent in the new subgenus. Ctenochira basipectinata Lee et Cha, 1993 (December) is synonymized with Ctenochira orientalis Kasparyan, 1993 (October), syn. n. A new genus Orthodoliusgen. n. (type species Cteniscus pectoralis Hellén, 1951) is established in the resurrected tribe Exenterini for two closely related species currently placed in Orthomiscus Mason, 1955 or Kristotomus Mason, 1962: Orthodolius pectoralis (Hellén, 1951), comb. n. and O.amurensis (Kasparyan, 1986), comb. n. The new genus is distinguished from Orthomiscus and Kristotomus by the more primitive structure of the mandibles and the almost unmodified apex of the hind tibia; it differs from all the genera of Exenterini in gregarious parasitism on Cimbicidae sawflies (as established for O.pectoralis). An important diagnostic feature of the genus Exenterus Hartig, 1837 is emphasized, namely the fusion (unmovable fixed connection) of the second and third metasomal tergites. This feature, not included by A. Bennett in his analysis of the subfamily, is extremely rare in Ichneumonidae (found in the genera Polyaulon Foerster, 1869 and Syndipnus Foerster, 1869, as well as in the Rhorusmesoxanthus species-group of the genus Rhorus Foerster, 1869), but constitutes a basic synapomorphy for the family Braconidae.

New trends in the technologies of mass breeding of entomophages and their use for biological pest control in greenhouses have been analyzed. The widespread use of new crop varieties, the spreading of new cultivation techniques in the Russian greenhouse crop production, and the increasing number of invasive pests make the selection criteria for entomophages more complicated and increase the need for adaptability of predators and parasitoids. The genetic selection methods of improving entomophages become more important in this context, including the methods for obtaining lines resistant to various phytosanitary preparations. The review covers the current range of entomophages and the directions of their further screening. A gap is noted between the current efforts in studying the ecology of entomophages and the information that is urgently needed for effective screening of species and their further adaptation in modern industrial greenhouses.

This paper presents comparative assessment of the timing of host abandonment by different taxa of ectoparasites of small mammals after the host has been captured in a regular snap trap. The data were obtained using a specially designed trap line with automatic logging of the capture time. Our results generally support the basic rule that ectoparasites eventually abandon the dead host. The most tangible and rapid reduction in infection rates following host death was observed in Ixodespersulcatus. Fleas and parasitic gamasid mites abandoned the host in 2–4 h, and lice, in 9–13 h after snap-trapping. Ixodes trianguliceps displayed no sharp decline in abundance for a prolonged period of time.

The sunn pest Eurygaster integriceps Put. is one of the most economically important insect pests of grain crops in many countries all over the world. This paper presents an analytical review of the world literature devoted to the harmful activity of the sunn pest and its biological background, in particular, variation in grain damage by the pest and methods of its assessment. All the currently known methods of detecting grain damage by the sunn pest (including visual assessment, radiography, infrared microscopy, and the express scanning method) have certain disadvantages and require improvement. Infrared microscopy and computer scanning methods provide the highest accuracy combined with the greatest ease of use in identifying damage caused by the sunn pest. [ABSTRACT FROM AUTHOR]

Four species of Tetranychidae are recorded for the first time from Kazakhstan: Eurytetranychus admes Pritchard et Baker, 1955, Eotetranychus thujae (McGregor, 1950), Oligonychus karamatus (Ehara, 1956), and Schizotetranychus schizopus (Zacher, 1913). The characters differentiating two morphologically similar species, the autochthonous Eurytetranychus furcisetus Wainstein, 1956 and the alien Eu. admes, are discussed.

Egriodesdollmani Marshall and E. septentrionalis Colonnelli have been collected in numbers on Gymnosporia senegalensis trees in Ethiopia. This is the first record of a host of the genus Egriodes, endemic to Africa. The weevils occurred mostly on the buds of the tree at the beginning of blossom in December. Egriodesdollmani and E.alticollis Marshall, apparently very similar to E. septentrionalis, were collected together also in Zimbabwe by Sir G.A.K. Marshall; E.dollmani and E. alticollis were collected together in two localities in Namibia by the Late Ch.W. O'Brien, L.B. O'Brien, and G.B. Marshall. Egriodesloisae Korotyaev, sp. n., is described from Namibia where it was the only species of this genus found near Grootfontein. Taken the broad range of Gymnosporia senegalensis, association of all the listed species with this plant looks probable and calls for the further search of Egriodes on it in other regions of Africa, southern Middle East, South and South-East Asia.

Nesting of a Brachyodynerus zhelochovtzevi (Kostylev, 1929) female was observed with timekeeping of its activity. The nest was located in the vertical wall of a crack in sandy-loam soil, in a flat spot with halophytic vegetation. The nest entrance was situated at a depth of about 1 cm from the soil surface and was a simple round opening, without an entrance turret. The nest tunnel was about 3 cm long and inclined downwards at about 45°. During the sealing of the cells and the whole nest, the female left the soil crack only to collect liquid for softening the soil; it obtained the liquid from succulent leaves of a plant of the genus Suaeda Forssk. ex J.F. Gmel. (Chenopodiaceae). The completed and sealed nest contained three brood cells, arranged in a row and sealed with soil partitions, and an empty vestibule sealed with a thicker final plug. The egg was attached with a thread to the lateral wall of the cell at its distal end. The female wasp hunted larvae of a single casebearer moth species of the genus Aporiptura Falkovitsh, 1972 (Coleophoridae), feeding on another species of Suaeda; 10–18 such larvae were stored in each brood cell. Adult wasps fed on nectar on the flowers of Limonium otolepis (Schrenk) Kuntze (Plumbaginaceae), Tamarix ramosissima Ledeb. (Tamaricaceae), and Lepidium obtusum Basiner (Brassicaceae). The biology of B. zhelochovtzevi is discussed and compared with that of B. magnificus (Morawitz, 1867) and members of other ground-nesting genera of Eumeninae. [ABSTRACT FROM AUTHOR]

A new subgenus Clypeostethasubgen. n. is established for the jewel beetle Sphenoptera epistomalis Obenberger, 1927 from Northwestern and Western Kazakhstan and northwestern Uzbekistan (the first record for the country). Principal diagnostic characters of the new subgenus, an illustrated redescription of S. epistomalis, and data on its distribution and host plant are presented. The main diagnostic character of Clypeostetha is the absence of the clypeal suture that separates the clypeus from the frons in all the other known Sphenopterini. [ABSTRACT FROM AUTHOR]

A new monotypic genus Deuterrisiusgen. n. with the type species Deuterrisius tobiasisp. n. is described. This is the second known representative of the tribe Risiini in the fauna of Australia and of Notogaea as a whole. The new genus is most closely related to the previously described, also Australian genus Austrorgerius Woodward; these two genera are united into a new subtribe Deuterrisiina subtrib. n. The new genus has a unique structure of the interalar scutellum whose apex, unlike that in all other Cicadina, is formed by a section of the metanotum; an incomplete realization of this structural variant is observed in the genus Austrorgerius.

This paper summarizes the material on empidoid flies of the families Brachystomatidae (2 species), Empididae (22 species), and Hybotidae (3 species) collected on Wrangel Island in the 20th (mostly in 1966, 1971, and 1972) and 21st (2006 and 2015–2020) centuries. The studied fauna is characterized by high species richness (at least double that on other Arctic islands) and the presence of probable endemics as well as North American species unknown from other regions of the Palaearctic. Despite clear correlation between the distribution of the commonest species and the gradient of mesoclimatic conditions, the activity of most of these species varies significantly even within one subzonal vegetation variant; this fact implies that they exist on the island outside their climatic optimum. Most of the rare species (one-third of the fauna), including the majority of probable endemics, were collected in the mountains of the southern part of Wrangel Island, which have the most varied relief and, correspondingly, a broad range of microclimatic conditions. Taxocenes with stable sets of the most abundant species (Rhamphomyia albopilosa, Rh.hovgaardii, Rh.nigrita, Rh.taimyrensis, Rh.septentrionalis, Rh.shewelli, Platypalpus subtectifrons) occur in the warmest central part of the island, constituting an enclave of the typical tundra subzone. The presence of common dominants determines their similarity with the Empidoidea taxocenes of the southern islands of the Canadian Arctic Archipelago. Some species (Rhamphomyia erinacioides, Rh.sublongiseta, Rh.gorodkovi, Rh.mallochi, Rh.frigida) prefer areas with the most rigorous climate and strong influence of the sea; among these species, only Rh.erinacioides is broadly distributed over the Arctic islands. High numbers of all these five species were recorded in the southwestern part of Wrangel Island (the northern variant of the Arctic tundra subzone); the taxocenes with a similar set of predominant species are unknown from other Arctic islands.

The paper reviews the available data on seasonal development of the best studied species of the subfamily Orthotylinae inhabiting the Palaearctic and Nearctic regions and included in 2 of the 6 tribes of this subfamily: Halticini and Orthotylini. All the 12 species of the tribe Halticini studied to date and included into this review are phytophagous with a wide range of host plants; all of them are characterized by wing polymorphism with long-winged males and, as a rule, short-winged females. Of these 12 species, 11 have a univoltine seasonal cycle and overwinter at the embryonic stage. When a species with a univoltine seasonal cycle penetrates beyond its native range, its seasonal development pattern remains close to the original one adapted to the environmental conditions of the species' native range. Microtechnites bractatus stands apart in the tribe Halticini because it represents the only genus in this tribe in which all the species are restricted to the Western Hemisphere, have a multivoltine seasonal cycle, and are zoophytophagous. Almost all the species of the tribe Orthotylini, regardless of their geographic distribution, have a univoltine seasonal cycle and are zoophytophagous, with the exception of Orthotylus flavosparsus, which has a multivoltine seasonal cycle and is phytophagous, preferring plants of the subfamily Chenopodioideae throughout most of its Holarctic range. Analysis of the data indicates that the seasonal development of Orthotylinae is still poorly understood, although among them there are many species that have great economic importance and invasive potential.

Seasonal changes in the coloration of the clypeus, mesonotum, and abdomen were studied in populations of the paper wasp, Polistes dominulus (Christ) in southern Ukraine. The color patterns in the populations were found to be different before and after hibernation. The frequencies of color morphs observed in the autumns of different years are similar, while the frequencies observed in spring vary from year to year. A tendency for pleometrosis is manifested by females of different color morphs in different years. The nest usurpers have darker patterns of the clypeus. A polyfunctional role of the coloration and pattern is supposed. [ABSTRACT FROM AUTHOR]
