Hello, Andre!

Any idea about the numbers of males/females you found, Juergen?
Not really, because I don't save the sex in my sighting records. I have looked at my photos from 2006/2007: the last flies in December are females, the last males date from end November. In early February 2007 there are equally males and females.
