Moths of the degraded woodlands in the polluted Sněžník area.
In a survey of moth species in the industrially polluted area around Sněžník in the north of Bohemia, conducted in 1986-2004, Minesotta light trap was used to capture some 400 thousand imagoes, and 35 thousand caterpillars were shaken out of birch crowns. The captured insect stages yielded 1270 species of moths of predominantly grassland and birch types. A number of them are regarded as serious pests on birch, pine and other trees. Industrial melanism was found on Alcis repandata, Biston betularius, Bupalus piniarius, Calliteara pudibunda, Lymantria monacha, Odontopera bidentata, Polia nebulosa, Sphinx pinastri and Tethea or. Both the rare and the commonly found moth species are illustrated in sections according to their typical habitat (birch, pine, horn beam/oak), and other relevant data, e.g. population dynamics, are in tables and graphs.
