Hi,
Yesterday I took insect pictures in a wetland in southwestern Germany and came across a remarkable tiny fly that was unknown to me. Some research led to Dolichocephala (Empididae), and I suppose it is either D. guttata or D. oblongoguttata, as the wings are only moderately spotted. BTW, GBIF still claims today that the latter species name is a synonym of the further, though Drake and Chandler (1997) made clear that both are valid species. I suppose we should follow their arguments, shouldn't we?
Another species that is said to occur in our region is D. thomasi. Can this be excluded? I did not find a key or a description pointing out the differences.
Thanks in advance for any comments! Sundew

Some more pics. My camera had difficulties focusing on the tiny fly, the Raynox macro lens reached its limits.
