Hello,
In the south of France, on February 19, 2022.
The body is 4 mm long.
Thank you for your help with identification.

Many thanks Tony,
I read that in France the two species Phortica variegata and semivirgo are confirmed since 1994. But I can't find the criteria that distinguish them! Is it the patterns of the thorax, the wing venation or others?
Is it a female or a male?

The continuous pale margin along the hind edge of the eye suggests it's semivirgo. And I can't decide, from what I can see, whether it's male or female.
