Hi,

Could it be a male of Ectophasia oblonga ?
(Belgium, Spa, 2017-07-17)

I think that it looks more like crassipennis male. The longitudinal stripe seems to be 1/5 of the abdomen width. The abdomen doesn't look longer than wide to me. Amazingly, the haustellum is always concealed behind something, so unable to determine length.

Wait for a specialist if they disagree.

although these Ectophasia are extremely variable, generally speaking males of oblonga are much redder. So I agree, this is most likely crassipennis.

Oblonga is not (yet) recorded from Belgium, is it ?

Thank you both,

I hesitated between oblonga and crassipennis because this male didn't look like the males of crassipennis that I usually see (the abdomen seemed longer and the sternite 3 narrower)

I don't know if Ectophasia oblonga has yet been seen in Belgium, but it is not reported from Belgium on the site of observation.be and of the Royal Institute of Natural Sciences of Belgium

Hello, I want to elaborate on this thread but I will create my own thread to avoid confusion. I'll edit this post with a link to my new thread after posting.

Only a little comment if somebody might be interested: this is being a catastrophic year for insects in Spain, but surprisingly it has been a good year for Ectophasia oblonga Smile First time ever that I see it in real life and not once but several times Smile No idea how it has been for the species in Central Europe.

And this one is E. crassipennis for me too. I always try to focus in abdomen's shape and avoid colours for the same reason Theo has mentioned (guess from whom I learned that Wink).

Hello Piluca, I must admit that this thread has me losing confidence with my judgement of Ectophasia. Have a look at my post when you have time. What is your opinion?

Dear Christine, I do have pictures but you get me at a pretty bad moment to process them Sad I will take note of this so that I don't forget and I shall post them as soon as I can (but it will be in days to come). Hopefully, this picture of E. oblonga can help to tell the difference Smile

The abdominal colour is usually more 'pinky' (hence the problem with the colours) but abdominal shape is diagnostic.

Best

Piluca

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
