Well, again I can learn something from your comment. In Central Poland there is so "huge" colony of this species that sometimes I just forget there such situation is not everywhere...
Amazing is that this species was discovered in Sweden in 1982! And interesting is if it was present in your country before, or maybe it just "conquers" this region of Europe.
Thank you very much for informative comment and for visiting of course :)
