Lepidoptera Community of the Woodland Complex Loučany near Klatovy

This thesis is focused on faunistic survey of Macrolepidoptera in Loučany (foothills of the Šumava Mts, Czech Republic). The research, involving different capture methods, proceeded from April to November 2015 on given transect and several other habitats. Based on the results (including partial data from 2013 and the last two decades of the 20th century), an inventory of identified species of Macrolepidoptera was made. Altogether 205 species from 16 families were found in Loučany. The most important species are for example the Black-veined White (Aporia crataegi), High Brown Fritillary (Argynnis adippe), Pearl-bordered Fritillary (Boloria euphrosyne), Purple Emperor (Apatura iris), Spruce Carpet (Thera britannica) and Sandy Carpet (Perizoma affinitata). The environmental parameters of experimental sites were noticed during research and the habitat preferences of species were analysed using specialized literature. Altogether 186 species (90,7 % of all identified species) are linked to some kind of woodland habitat. To support present biodiversity of the community of Macrolepidoptera, it is necessary to practice a suitable woodland management, conserving mosaicity and open canopy.
