Ábrahám Levente – Farkas Sándor: Butterflies along the river Drava, 2008

Copper buttennes are small species with vivid red coloration.The large copper (lycaena dispar) [5j is a threatened species throughout Europe. It is a species typical of wet meadows and forest edges. Wings of the males are uniform red, with only a black discal spot being visible. On the upper side of the females' wings there are several dark spots. The underside of the hindwings is bluish, with characteristic white-edged black dots (ocelli) being present on them. There are two generations developing within a year. Individuals of the first generation show territorial behaviour, whereas those from the second batch will roam about. Populations of the large copper are threatened mostly by water regulation works carried out in their habitats. It is a Natura 2000 species, and its population shows a decreasing trend along Dravariveraswe
