This Alpine species was probably introduced in some other European countries such as France, Great Britain and Spain in the second half of the 20th century. It was also found in the same period in our country, this became clear when specimens were caught at Oegstgeest (province of Zuid-Holland) in 1982. Ten years later the species was known already from 60 localities across the provinces other than Flevoland, Groningen and Friesland. Another ten years later it was also known from the remaining provinces including the Wadden isles of Texel and Terschelling. Nowadays, it is a common member of the Dutch fauna. |
