Woodland Brown Lopinga achine (Nymphalidae, Satyrinae) still surviving in the Hlučín region?

The study is focused on the distribution of the critically endangered Lopinga achine in the Hlučín region, near the border to Poland. Lopinga achine has been considered extinct there since the early 1970s. The paper provides data on the current distribution at several new localities in the vicinity of Vřesina near Opava, Píšt, Hať and Děhylov (Silesia). The population of L. achine is not abundant in the Hlučín region. Host plant of the larvae is the sedge Carex brizoides, which makes it different from most other European populations. Currently, two isolated populations of L. achine survive in the Czech Republic (i.e. populations in Silesia and southeastern Moravia). Both the populations are threatened with extinction due to changes in forest management.
