The July and most of August 2010 was extremelly hot and dry in Central Russia: according historical data the hottest during 500 year, according other methods the hottest for at least last 5000 years.
I'd like to report the consequences of this drought. Now in mid June the amount of flies is about 10 times less than usually and the collecting in Moscow region is generally useless this year. This opinion is also shared by my friend and colleagues Andrey Ozerov and Dmitry Gavryushin. My group - Mucsidae suffered badly, Dima's Limoniidae substantially. On the contrary, some hot&dry-loving groups as Asilidae or wasps seems unusually numeruous.
