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.


Louis Weitten : France : Florange : 57190 : 28/05/2023
Altitude : 165 m - Taille : 5 à 6 mm (LAA)
Réf. : 323642

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 Nikita
what do you mean ?
what do you think of the last picture of the head (two fly i have caught in my apartment)
Is it the same species?, a male and a female?, or an interspecific variation ?
Thank you
Louis

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.
