A faunistic review of ground beetles of Lebiinae Bonelli, 1810 (Coleoptera: Carabidae) of Lithuania

The paper presents the first review on species composition and distribution of ground beetles of Lebiinae Bonelli, 1810, subfamily (Coleoptera: Carabidae) in Lithuania. During the study, all available related published sources have been reviewed. A total of 482 records have been analyzed and more than 700 specimens collected since 1923 have been examined. Lebiinae subfamily is presented by 2 tribes in Lithuania. The tribe Odocanthini is monotypical with a single species. The other one, Lebiini tribe, is more diverse, represented by 4 subtribes, 7 genera and 24 species. The information on distribution, frequency and some features of ecology and zoogeography of 25 Lebiinae species found in Lithuanian is detailed. Demetrias atricapillus (Linnaeus, 1758) is reported for the first time for Lithuanian fauna and Philorhizus notatus (Stephens, 1827) is removed from the list of Lithuanian beetles

An annotated checklist of Prioninae Latreille, 1802 (Coleoptera, Cerambycidae) of Lithuania

We present the first annotated checklist of the subfamily Prioninae Latreille, 1802 (Coleoptera, Ceram-bycidae) in Lithuania. At least 140 published and unpublished records of Prioninae were analyzed and collected specimens were verified. As a result, one species, Aegosoma scabricorne (Scopoli, 1763), was found to be new for Lithuanian fauna and three species, Ergates faber (Linnaeus, 1761), Tragosoma depsarium (Linnaeus, 1767), and Prionus coriarius (Linnaeus, 1758), were confirmed in the country. The information on the local occurrence, natu-ral history, general distribution, and conservation status of these species is reviewed.&nbsp

First records of pseudoscorpions (Arachnida: Pseudoscorpiones) from Lithuania

First records of pseudoscorpions from Lithuania are presented based on specimens preserved in Lithuanian collections and new material collected during the latest ten years. Pseudoscorpions were collected at 25 localities in both deciduous and coniferous forests at altitudes of 5 to 186 m above the sea level. Sifting of litter and moss, pitfall traps and collecting by picking under the bark of deadwood were used as the collecting methods. Altogether 132 specimens belonging to eight species from three families were recorded. The findings of Neobisium crassifemoratum (Beier, 1928) represent the northernmost known records of the species

New record of Calosoma (Campalita) auropunctatum (Herbst, 1784) in Latvia with notes on its occurrence in the Eastern Baltic region

Background and purpose Calosoma auropunctatum (Herbst) is the species with no confirmed records in the last 150 years in Latvian fauna. Until now the species was considered possible extinct in this area. The species was confirmed for Latvia in 2014, during the research project devoted to biodiversity monitoring in various agrocenoses with different management systems. The paper is aimed to clarify habitat peculiarities of the species in Latvian fauna and discuss the possibilities of widest distribution of this species in Easter Baltic region.Materials and methods The study site is located in the eastern part of Latvia, from May 2014 to August 2015. The ground beetles were collected using pitfall traps, installed in 2 linear transects located at field margin and in the field central part, more than 100 m. far away from the field border.Results One male and three females were caught by pitfall traps during vegetation period in cource of 2014-2015 years. Calosoma specimens deposited in coleopterological collections in Latvia were reviewed. Previous record of this species in Latvia based on specimen deposited in Latvian Museum of Natural History is disproved. In addition the paper presents information on the geographical distribution and biology of the species.Conclusions The first proven findings of C. auropunctatum in Latvia was presented during two field season’s, that suggest a presumption of occurring of small, local population of this species in territory of Latvia.</p

Effect of forest clear cuts on plant–pollinator interactions: the case of three ericaceous subshrubs in Lithuanian pine forests

Managed boreal pine forests are subject to regular clear cuts causing significant disturbances to these ecosystems. It is believed that, to some extent, they resemble natural cycles of forest growth, decline, and regeneration and can benefit, e.g., mutualistic relations among plants and pollinators. To study the impact of forest management (clear cuts) on pollinator visitation, we focused on three ericaceous plant species, Vaccinium myrtillus, V. vitis-idaea, and Calluna vulgaris, common elements of pine forest understory. Our observations, conducted in Lithuania, showed that there are no differences among control mature stands and clear cut areas in terms of visitation frequency for all three studied species. However, at least for C. vulgaris, a shift toward fly visits was observed in the clear cut site, showing that open areas are preferred habitats for these insects. Ants constituted an important share of visitors to flowers of V. myrtillus and C. vulgaris, suggesting their important role in reproduction of these plant species

Carabid beetles species diversity and abudance in some agrobiocenoses

n 1998-1999, in Kaunas district (Lithuania), in winter wheat, summer barley, winter rape and summer rape fields, the carabid beetles species diversity and abudance were investigated. In total 14034 beetles, belonging to 22 genus and 64 species were trapped. In summer rape - 41 and winter wheat - 38 carabid species were found mostly. Less species of carabids were fuond in summer barley (36 species) and winter rape (37 species). Carabids were most numerous in winter wheat (4953 specimens) and winter rape (4953 specimens trapped in 3 traps). In summer barley - only 1845 and summer rape - 2605 carabids. Dominating Pterostichus genus was in all agrobiocenosesVytauto Didžiojo universitetasŽemės ūkio akademij

ZachResearch, monitoring and development of preservation strategies for threatened species are often limited by national borders even though a global perspective would be more appropriate. In this study, we collected data on the occurrence of a threatened beetle, Osmoderma eremita, associated with tree hollows in 2,142 localities from 33 countries in Europe where it is or has been present. The larvae develop in tree hollows and very few observations of larvae have been observed in dead logs on the ground. As long as there is a suitable tree hollow, it appears that O. eremita may use any tree species. Oaks (Quercus spp.) are the trees mainly used by O. eremita, followed by lime (Tilia spp.), willow (Salix spp.), beech (Fagus sylvatica)and fruit trees (Prunus spp., Pyrus spp., Malus domestica). O. eremita is still found in some remnants of natural forest, but is mainly observed on land that has long been used by man, such as pasture woodlands, hunting parks, avenues, city parks and trees around agricultural fields and along streams. The occurrence of O. eremita seems to have decreased in all European countries. Relatively high densities of O. eremita localities occur in Central Europe (northern Italy, Austria, Czechia, southern Poland and eastern Germany), some parts of Northern Europe (south-eastern Sweden, Latvia) and France. In some regions in north-western Europe, the species is extinct or may occur at some single sites (Norway, Danish mainland, The Netherlands, Belgium, north-eastern France). There are few data from south-eastern Europe. Many local extinctions of O. eremita are to be expected in the near future, especially in regions with recent habitat loss and fragmentation. O. eremita is useful as an indicator and umbrella species for the preservation of the entire invertebrate community associated with hollow trees in Europe. A preservation plan for O. eremita should include three aspects that are of general importance in nature conservation in Europe todVytauto Didžiojo universitetasŽemės ūkio akademij

Pušinis plokščiavabalis : Cucujus haematodes (Erichson, 1845)

Found only sporadically in the southern part of Lithuania, this species inhabits old woodlands, where its larvae develop for up to three years under the bark of dead trees, both coniferous and deciduous (in Lithuania this species has been found exclusively under the bark of dead pines). The main reasons for its decline are a loss of suitable habitat due to forest management and clear-cutsBotanikos sodasKauno Tado Ivanausko zoologijos muziejusVytauto Didžiojo universiteta
