Hello
The 2023/05/15, I posted in this message a male of Fannia canicularis
https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=109860

The 2023/05/28, I once again caughted the same fly (I think ?) in the same place (NE of France my apartment Florange 57190). Length body : 5 à 6 mm.

I compared the 2 heads and I noticed that the fly from 05/28 has a long yellowish stripe that extends from the back of the head to the apex of the antennae while the other doesn't have this stripe.

What do you think ?
Is it the same species?, a male and a female?, or an interspecific variation
Thank you very much

Hello Louis, both are males (the female has a distinctly wider frons) and I think the differences depend on the angles and the lighting of the photos.
Greetings, Eric Kloeckner

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
