TL;DR: The distribution of E. maturna is tightly linked to its ecology, which differs substantially from the ecology of the same species in central Europe as mentioned in this paper, where the main larval host plant is Melampyrum pratense (Orobanchaceae), which is common throughout Finland.
Abstract: The scarce fritillary Euphydryas maturna (L.) is a highly endangered species of butterfly in several European countries. However, in Finland it occurs commonly in the southeastern part of the country and its distribution has remained stable over the past 40 years. The ecology of E. maturna has recently been studied in Finland. In this paper, I review these studies and show that the distribution of the species is tightly linked to its ecology, which differs substantially from the ecology of the same species in central Europe. In Finland, the main larval host plant is Melampyrum pratense (Orobanchaceae), which is common throughout Finland. Euphydryas maturna is restricted to south facing forest edges where the sharp ecotone provides a warm habitat. Larvae need warm microhabitats to be able to grow fast in the spring. Natural forest edges are formed by rocky outcrops, which are common in SE Finland. The distribution of E. maturna coincides with the area where rocky outcrops are common. I suggest that the presence of the granite bedrock close to the surface of the ground largely explains the present distribution of E. maturna in Finland. I also note that the species benefits from clearcuts made in the forests and conclude that E. maturna is not threatened in Finland at the moment.

TL;DR: This paper describes insect communities inhabiting two old-growth forest polypores Amylocystis lapponica and Fomitopsis rosea (Polyporaceae) and reports the rearing results and discusses the biology of the beetle Hallomenus sp.
Abstract: This paper describes insect communities inhabiting two old-growth forest polypores Amylocystis lapponica and Fomitopsis rosea (Polyporaceae). Basidiocarps of both species were collected from old-growth forests in southern and eastern Finland and Russia. Samples of A. lapponica and F. rosea basidiocarps revealed insect communities of more than 50 species each, including many rare old-growth forest species. Here we report the rearing results and discuss the biology of the beetle Hallomenus sp. (Melandryidae) inhabiting A. lapponica and the beetle Cis dentatus (Cisidae), the moth Agnathosia mendicella (Tineidae) and the fly Elfia cingulata (Tachinidae) inhabiting F. rosea. Distribution maps of C. dentatus and A. mendicella in Finland are given.

TL;DR: Adult craneflies were collected along 27 springs and springbrooks in 1999 and 2000 in southern Finland and 95 species, including Erioptera pederi Tjeder, Molophilus bifidus Goetghebuer, and Lipsothrix ecucullata Edwards are reported for the first time from Finland.
Abstract: Adult craneflies were collected along 27 springs and springbrooks in 1999 and 2000 in southern Finland (biogeographical provinces of Ab, N, St and Ta). A total of 95 species (24 Tipulidae, 2 Cylindrotomidae, 54 Limoniidae, 12 Pediciidae and 3 Ptychopteridae) and 2714 individuals were identified. The material was collected by Malaise and window traps and by sweep netting. Tricyphona immaculata (Meigen), Pedicia rivosa (Linnaeus), P. straminea (Meigen) and Paradelphomyia fuscula (Loew) were the most common and often most abundant species. Erioptera pederi Tjeder, Molophilus bifidus Goetghebuer, M. bihamatus de Meijere, M. corniger de Meijere, Lipsothrix ecucullata Edwards, Dicranota pavida (Haliday) and Ula mixta Stary are reported for the first time from Finland.

TL;DR: Observations on the larval gregarious behaviour, host plant use and parasitoids of six species of melitaeine butterfly in the Russian Republic of Buryatia show post-diapause larvae in two habitats, steppe and taiga forest region.
Abstract: We report observations on the larval gregarious behaviour, host plant use and parasitoids of six species of melitaeine butterfly in the Russian Republic of Buryatia. We observed post-diapause larvae in two habitats, steppe and taiga forest region. Five species were found in the steppe region: Euphydryas aurinia davidi, Melitaea cinxia, M. latonigena, M. didymoides and M. phoebe. Three species (M. cinxia, M. latonigena and M. didymoides) fed on the same host plant, Veronica incana (Plantaginaceae). Euphydryas aurinia larvae were found on Scabiosa comosa (Dipsacaceae) and M. phoebe larvae on Stemmacantha uniflora (Asteraceae). Three species were found in the taiga region (M. cinxia, M. latonigena and M. centralasiae), of which the first two fed on Veronica incana. Five species of hymenopteran parasitoids and three species of dipteran parasitoids were reared from the butterfly larvae of five species.

TL;DR: Life history records indicate that the Elachista regificella complex has, at least to some extent, different host plant preferences: Luzula sylvatica is recorded as the host plant of E. tengstromi in Europe, with further host plants recorded in Japan.
Abstract: The Elachista regificella complex (Elachistidae) is revised and considered to consist of three closely related species: E. regificella Sircom, presently only recorded from Great Britain, E. geminatella (Herrich-Schaffer), stat. rev. (= E. nieukerkeni Traugott-Olsen, syn. nov.) and E. tengstromi nom. nov. (= E. magnificella Tengstrom, 1848, nec Duponchel, 1843). The latter two species are widely distributed e.g. in Central Europe, the range of E. tengstromi extending to Japan. The species are diagnosed and illustrated. Life history records indicate that the species have, at least to some extent, different host plant preferences: Luzula sylvatica is recorded as the host plant of E. regificella and E. geminatella, of which the latter probably exploits other host plants as well. L. pilosa is the only known host plant of E. tengstromi in Europe, with further host plants recorded in Japan. Neotypes are designated for Elachista regificella Sircom and Poeciloptilia geminatella Herrich-Schaffer.

TL;DR: During a survey in forests of different ages in southeastern Norway, the fungivorous thrips Hoplothrips polysticti was found to be common in dead Picea abies infested by Trichaptum abietinum, especially in a semi-old forest.
Abstract: The fungivorous thrips Hoplothrips polysticti has previously been reported only from Scotland and Sweden. During a survey in forests of different ages in southeastern Norway, the thrips species was found to be common in dead Picea abies infested by Trichaptum abietinum, especially in a semi-old forest. Hoplothrips unicolor was also recorded for the first time in Norway. The occurrence of H. polysticti is discussed in relation to the age of the forests, and to the biochemical interference between fungi impacting the nutrient quality for the thrips. H. polysticti is proposed as a vector for T. abietinum.

TL;DR: It is reported that the fly reared from the larvae and/or pupae of the chrysomelid Melasoma populi L. lapponica in Russia is Megaselia opacicornis Schmitz and fuller details on its biology are provided.
Abstract: Most records of Phoridae reared from beetles are cases of moribund individuals of the ‘host’ species utilised by the larvae of saprophage phorid species (e.g. Durska & Disney 1998). The notable exceptions are the parasitization of the pupae of Coccinellidae (Disney 1994, Disney et al. 1994), of the adults of Cantharidae (Borgmeier 1958, Brown 1996b) and of Lampyridae (Lloyd 1973, Lewis & Monchamp 1994, Brown 1996a), and the parasitization of the pupae of the chrysomelid Chrysomela aenea L. (= Melasoma aenea L.) by Megaselia rubricornis (Schmitz) (Kanervo 1946). A second possible case reported an unidentified phorid reared from the larvae and/or pupae of the chrysomelid Melasoma populi L. (Devantoy 1948), but it is difficult to assess as to whether this was a case of parasitoidism or exploitation of moribund hosts by a saprophage species. However, a further definite case of the parasitization of the pupae of a chrysomelid involves M. lapponica (L.) in Russia. Initially, the phorid species involved was also attributed to M. rubricornis (Zvereva et al. 1995, 1997). However, since then further specimens were submitted to MBM, who in turn passed a sample to RHLD. The latter concluded that they were not M. rubricornis. In the present paper we report that this fly is Megaselia opacicornis Schmitz and provide fuller details on its biology.

TL;DR: The genus Meteorus includes several species yet to be found from Finland, which almost certainly originated from the larvae of Pytho depressus (Coleoptera, Pythidae), which has previously been recorded from the family Pythidae.
Abstract: Meteorus corax (Hymenoptera, Braconidae) is reported for the first time from Finland and Russian Karelia. The Finnish specimens were reared from standing dead pine where Monochamus galloprovincialis (Coleoptera, Cerambycidae) was presumably the host, and in addition, from firewood presumably from Callidium violaceum (Coleoptera, Cerambycidae). The specimens from Russian Karelia were reared from pupae, which almost certainly originated from the larvae of Pytho depressus (Coleoptera, Pythidae). No parasitic hymenopterans have previously been recorded from the family Pythidae. The genus Meteorus includes several species yet to be found from Finland.

TL;DR: The material of B. sinuata collected from bracket fungi shows an interesting habitat choice of a sciarid species and suggests a rarely documented case of a host-parasite relationship between aSciarid fly and an ichneumonid wasp species, Stenomacrus curvulus (Thomson).
Abstract: Menzel & Mohrig (1997) described Trichosia (Baeosciara) sinuata in their revision of the Palearctic species of Trichosia Winnertz (Menzel & Mohrig 1997, Mohrig & Menzel 1997). New material of the species reared from fruiting bodies of Fomitopsis rosea (Alb. & Schw.:Fr.) P. Karst (Polyporaceae) led us to the conclusion that the species needed to be redescribed. In general, the state of the classification of Sciaridae is far from satisfactory, many of the current genera are obviously not monophyletic (Vilkamaa 2000). At the species level, identification is often difficult because high-quality revisions and identification keys are lacking. The phylogenetic and taxonomic problems regarding the Trichosia group of genera, including Baeosciara Tuomikoski, are neglected here and will be discussed by PV in a later paper. The details of the biology of Sciaridae are poorly known (see Steffan 1981). The larvae live mostly in soil and litter, under the bark of trees or in the sporocarps of fungi. The material of B. sinuata collected from bracket fungi shows an interesting habitat choice of a sciarid species and suggests a rarely documented case of a host-parasite relationship between a sciarid fly and an ichneumonid wasp species, Stenomacrus curvulus (Thomson).
TL;DR: A list of 13 species of the family Scythrididae collected during 29.IV.
Abstract: A list of 13 species of the family Scythrididae collected during 29.IV.– 04.V.2000 in Tunisia is presented. Two new species are described: Scythris kefensis sp. n. and S. spectatorella sp. n.. Both of them are small, dark moths belonging to the subfasciata species-group. S. aciella Bengtsson, 1997 and S. azrouensis Bengtsson, 1997 are recorded for the first time from Tunisia. Further notes on these and some other taxa are given.

TL;DR: Bocchus vernieri Olmi, 1995 was found in Ta: Tammela, southern Finland, as the first species of the subfamily Bocchinae for Fennoscandia; it is a new species for N. Europe as mentioned in this paper.
Abstract: Bocchus vernieri Olmi, 1995 was found in Ta: Tammela, southern Finland, as the first species of the subfamily Bocchinae for Fennoscandia; it is a new species for N. Europe. Gonatopus horvathi Kieffer, 1906 is added to the fauna of Finland; it is also a new species for Northern Europe. The two species are further described on the basis of the new material. The generic position of North European species of Gonatopodinae is re-evaluated, and it is concluded that a single genus, Gonatopus Ljungh, should be recognized, to include two subgenera, Dicondylus Haliday (Haplogonatopus R. C. L. Perkins, syn. nov.) and Gonatopus s. str. In the Appendix Bocchus italicus Olmi, 1984 is reported from Corfu as new to the fauna of Greece.

TL;DR: A new cochylid taxon occurs on dry steppe slopes in the headland region of the southern Urals, and it is rather easy to separate from closely related taxa both externally and by the male genitalia.
Abstract: Nupponen, K., Junnilainen, J., Nupponen, T. & Olschwang, V. 2001: The cochylid fauna of the Southern Ural Mountains, with description of Cochylimorpha ignicolorana Junnilainen & K. Nupponen sp. n. (Lepidoptera: Tortricidae: Cochylini). — Entomol. Fennica 12: 94‐107. A list of 78 species of the tortricoid tribe Cochylini from the southern Ural Mountains is presented. The material was collected during 1996‐2000 on nine different Finnish-Russian expeditions. Cochylimorpha ignicolorana Junnilainen & K. Nupponen sp. n. is described. The new taxon occurs on dry steppe slopes in the headland region of the southern Urals, and it is rather easy to separate from closely related taxa both externally and by the male genitalia. In addition, 7 species are reported as new for Europe and 4 species as new for Russia. The known distribution range of each species is given as well as
TL;DR: The findings support the view that the species has a two-year life cycle with two obligatory winter diapauses and that X. borealis seems to prefer buds and fresh shoots of spruce in its diet.
Abstract: Observations on a larva of Xestia borealis found in nature are presented. Our findings support the view that the species has a two-year life cycle with two obligatory winter diapauses. Like Xestia sincera, X. borealis seems to prefer buds and fresh shoots of spruce in its diet. Both species overwinter for the first time as large III–IV instar larvae, after overwintering rapidly complete their larval development, and subsequently fall into a long summer diapause. We also discuss some features of larval biology of other boreal Xestia species with a two-year life cycle.
TL;DR: A population of Pterophorus volgensis was found at the end of May 1998 at Mount Verbljushka in the Orenburg oblast in the southern Ural Mountains, and in the next spring, 22 larvae of this rare taxon were found on Rindera tetraspis in the same locality, and 11 moths were bred.
Abstract: A population of Pterophorus volgensis (Möschler, 1862) was found at the end of May 1998 at Mount Verbljushka in the Orenburg oblast in the southern Ural Mountains. In the next spring, 22 larvae of this rare taxon were found on Rindera tetraspis (Pallas) in the same locality, and 11 moths were bred. The biology and the distribution of the species are discussed. The larva of P. volgensis is described on the basis of material preserved in ethanol. Some drawings of mouthparts and chaetotaxy are given.

TL;DR: Swammerdamia glaucella and S. buraetella are described on the basis of material collected from the southern Ural Mountains and southern Siberia as discussed by the authors.
Abstract: Swammerdamia glaucella sp. n. and S. buraetella sp. n. are described on the basis of material collected from the southern Ural Mountains and southern Siberia. S. glaucella occurs in forest steppe slopes and bushy meadows in two generations from the end of May to the beginning of July and late July. The species is widely distributed in southern Russia and the adjacent regions. S. buraetella is only known from Buryatia where it seems to favour open steppe habitats. The species occurs in two generations from the end of April to the end of May and in July. Both new taxa differ from their known relatives both externally and on the structures of genitalia. The Russian records of Kessleria caflischiella (Frey, 1880) are discussed.
TL;DR: The Swedish-Canadian icebreaker-based expedition to the Nearctic in summer 1999 (July and early August) collected moths and butterflies (Lepidoptera) during short, helicopter-aided visits to eight sites in the Canadian archipelago, three sites on the Canadian mainland near the arctic coast and also at Thule Air Force Base in north Greenland as mentioned in this paper.
Abstract: During the Swedish-Canadian icebreaker-based expedition to the Nearctic in summer 1999 (July and early August), moths and butterflies (Lepidoptera) were collected during short, helicopter-aided visits to eight sites in the Canadian archipelago, three sites on the Canadian mainland near the arctic coast and also at Thule Air Force Base in north Greenland. Some of the visited sites (notably those on Melville Peninsula, Somerset Island and King William Island) have not previously been investigated with respect to their insect faunas. Several records thus represent species range extensions. They generally corroborate an earlier hypothesis, based on a floristic zonation scheme, which has been used as a framework for understanding the distribution of Arctic butterflies.
TL;DR: Proclithrophorus genalis sp.
Abstract: Proclithrophorus genalis sp. n. is described on the basis of one female from Pudasjarvi, northern Finland. The new species is compared with eastern Palaearctic type species of the genus, P. mandibularis Tobias et Belokobylskij, 1981.

Abstract: The Pionini species (Ichneumonidae, Ctenopelmatinae) Lethades cingulator Hinz, L. curvispina (Thomson), Trematopygus helleni Hinz, T. rufator Hinz, Rhorus chrysopygus (Roman) and Rh. lapponicus (Roman) have been reported from Finland.
TL;DR: The examination of some unidentified Asian Gyrinus specimens in the Zoological Institute of St Petersburg revealed the presence of one more species in Mongolia, which will be described here as new.
Abstract: In his review of Mongolian Gyrinidae, Guéorguiev (1968) included the following seven species: Aulonogyrus concinnus (Klug); Gyrinus minutus Fabricius, 1798; G. paykulli Ochs, 1927; G. distinctus Aubé, 1838; G. marinus Gyllenhal, 1808; G. aeratus Stephens, 1835; and G. opacus C. R. Sahlberg, 1819. Later, Guéorguiev (1969, 1972) added one more record each from Mongolia of G. aeratus and G. distinctus. The examination of some unidentified Asian Gyrinus specimens in the Zoological Institute of St. Petersburg revealed the presence of one more species in Mongolia, which will be described here as new. The new species is very similar to G. distinctus, with which it will be compared. Moreover, the single female of G. distinctus recorded from UlanBaator by Guéorguiev (1968) in fact belongs to the new species.

TL;DR: The larva of Siobla ruficornis is redescribed on the basis of specimens collected in East Finland on 14 August 1999 and the habitus of Finnish larvae conforms closely to Malaise’s description.
Abstract: The larva of Siobla ruficornis (Gimmerthal, 1834) is redescribed on the basis of specimens collected in East Finland (PS:Heinavesi) on 14 August 1999. Four larvae were found on Prunus cerasus and one on Rubus idaeus. Malaise (1932) briefly described ornaments of a larva found on Epilobium angustifolium in NE Asia. The habitus of Finnish larvae conforms closely to Malaise’s description. Further characteristics are added here and drawings of mouthparts and colour picture of larva are given.
TL;DR: A new taxon of a small, dark pterophorid moth from the Kurai region in the SE Altai Mountains is described, based on the forewing veins R1, R2 and R3 fused with vein R4, external appearance of the moth and details in the male genitalia.
Abstract: In late June 2000, two specimens of a small, dark pterophorid moth were collected from the Kurai region in the SE Altai Mountains. The taxon belongs to the genus Pterophorus, based on the forewing veins R1, R2 and R3 fused with vein R4, external appearance of the moth and details in the male genitalia such as a robust, moderately short saccular process and a very long, curved aedeagus. Externally it resembles P. volgensis (Moschler, 1862) and P. taklamakanus (Arenberger, 1995), the former known from the southeastern part of the European Russia and the latter by a single specimen from Tibet (Arenberger 1995). However, the male genitalia of the Altaian specimens are clearly different from those of closely related species. The new taxon is described in this paper.
