Exotic butterflies move higher in the warmer winter
Due to warmer winter conditions, butterflies from Africa and the Mediterranean are making themselves at home in the Austrian Alps, one of Western Europe’s coldest region.
From the Planetark article - “We have seen some very unusual species and … we are talking about species that shouldn’t even be able to survive the winter here, which is what surprises us” said Peter Huemer, biologist at the Tyrolean State Museum.
