Sixteen species of Lepidoptera, belonging to 10 families, were recorded on snow in Central Poland. Two episodes of mass occurrence on snow were observed: adults of Operophtera brumata and larvae of Euthrix potatoria. Twelve species were recorded from snow for the first time in general. Three ecological groups of snow active Lepidoptera were distinguished: 1) autumn and winter active moths, 2) overwintering species which could be periodically activated from diapause, and 3) early spring active species. The ecology of winter active Lepidoptera is discussed. All were classified as chionoxenes, while O. brumata was considered as the moth most regularly recorded on snow andmost likely to be met in winter.

Achecklist of 190 species of Estonian caddisflies is compiled based on literature and voucher material in collections at Estonian University of Life Sciences. 31 species are listed first time for the country while 159 taxa were referred to in literature. Two taxa are rejected as possible misidentifications (Diplectrona felix and Molanna submarginalis). 25 species are listed in Estonian Red Data book. Geographical distribution of Trichoptera both in Estonia and along the east shore of Baltic Sea is reviewed in brief.

Data concerning the occurrence and abundance of the taiga tick Ixodes persulcatus in eastern Finland (North Karelia and Kainuu regions) are presented. Sampling was carried out in May 2008 and June 2009, around the University of Joensuu Mekrijärvi Research Station and the City of Kuhmo. In 2008 and 2009, the abundance of adult taiga ticks in the first study area was 0.17 and 0.13 ticks per flag-km, respectively. Only a single I. persulcatus specimenwas found in the second study area (abundance was 0.02 specimens per flag-km). All ticks (635 specimens) collected from cats and dogs in south-eastern Finlandwere identified as Ixodes ricinus.

The first larval instar of the ground beetle Broscus crassimargoWollaston, 1865 endemic to La Gomera (Canary Islands, Spain) is described. This is the first comprehensive study of the primary chaetotaxy of the three tagmata ever carried out in larvae of Broscini, being also accompanied by a detailed iconography. The implications of the results of this chaetotaxy analysis are discussed in relation to the possible origin of Broscini within Carabidae. Comments on the ecological determinants for its remarkable presence in the mesovoid shallow substratum are given, analysing the differences between La Gomera and other Canary islands where samplings in the same subterranean habitat have been carried out.

We report on changes in the volatiles emitted by wheat plants of the cultivar ‘Tonacja’ after the plants were scraped, pierced or damaged by adults of Oulema melanopus (Linnaeus). The blend of volatiles was dominated by typical green leaf volatiles and in addition contained linalool and B-caryophyllene, but the latter two were released in large amounts only after more than one day of insect feeding. Overall, the plants that had been damaged by the insect released more odors than the plants that were subjected to mechanical damage. Moreover, control plants released significantly lower amounts of volatiles. Scraping of leaves induced higher volatile emission than puncturing the leaves. A Y-tube bioassay was used to evaluate upwind orientation ofadult cereal leafbeetles. Greater number of female 0. melanopus was attracted to (Z)-3-hexenal and (Z)-3 -hexenyl acetate at low concentrations. Higher concentration of these compounds and linalool significantly repelled both females and males.

Seed production of alfalfa (Medicago sativa L.) is important in determining the effective distribution of new cultivars to farmers. However, little is known about the biodiversity and their community function of native wild pollinators of alfalfa in agronomic systems. We investigated the biodiversity of insects which visited alfalfa flowers and their temporal foraging characters in Hexi Corridor, China. A high biodiversity of insect visitors was discovered, 20 insect taxa in all, including 13 species of Hymenoptera, 3 species of Coleoptera, 3 species of Lepidoptera and 1 species of Diptera. Three native bee species, Andrena squamata, Anthophora melanognatha and Megachile abluta,were validated as the principal pollinators. They showed significant variations in tripping mode and their diurnal distribution patterns. Our results indicated that the native wild bees are diverse and they complement each other. This means they have developed a more complex system for the pollination of alfalfa than has been previously found out.
