Hi, Today I visited the heavily exudating elm tree of thread http://www.dipter...d_id=38628 and was delighted to find a male of Sphiximorpha subsessilis again! Furthermore, there was a grey and yellow fly hovering around the trunk, and when it sat down and allowed for some photos I saw the vena spuria of a Syrphid. So Brachyopa bicolor, feeding on tree saps, would fit perfectly! What do you say? Regards, Sundew Sundew attached the following image:  [169.37Kb] |

It's very difficult to say... so, it's necessary to observe the arista with a microscope. But perhaps someone could be identify it without the microsopical characters !  |

I see... I did not know that there are so many similar species. Meanwhile I found out that as much as nine species are listed for Berlin. So this interesting fly must remain a Brachyopa spec. Many thanks, Valentin! |
