Stenophylax vibex (Curtis, 1834)

The species is recently confirmed as new to Poland ( Górecki & Czachorowski 2010). In the ŚPN single specimens were caught at almost all the localities except Podgórze and Las Serwis in late May and June. Large swarms were observed in September and October, and some specimens were caught as late as November. The largest number of individuals was trapped at Dąbrowa (133♂, 10♀) in 2008. A total of 456 specimens were caught. To this day S. vibex has not been recorded anywhere else beyond the boundaries of the ŚPN. It frequently comes to light, but all the very many attempts to attract it to light traps in other parts of Poland have failed. In Germany the species is endangered and is listed in that country’s Red Data Book ( Klima 1998). In one of the German Länder – Sachsen-Anhalt – it is found only in the Harz Mountains, in streams with stony or gravelly beds ( Hohmann et al. 2004).
