it seems North Europe is heating more comparing with the South Europe.. maybe.
I would like to hear if any more Northern dipterologists have similar reports with yours.
But here in South it is clear: much more fewer flies than usual! And not just in the number of individuals. Yes, it is true that I have found some new genera that I never saw in the last 4 years. However, there are so many common flies that apparently disappeared...


You can exclude the small bits of rock in the North Sea where I live as far as heating up goes. We have had a very long spell of cold weather...snowed off and on for 8 months (October - May) and very little sunshine all summer. Fly numbers seem to be about the same as last year, with more Syrphids about. I noted last year was a poor year for these..http://www.dipter...d_id=28035 and that the same may show in other regions...apparently I was right...ish.
The number of flies up here fell dramatically today, this was due to yours truly being on the wrong end of a paintbrush all day...lots of white flies...hard to ID them though..:|
