Hello,
I found a Chenopodium specimen with some fly larvae feeding inside the leaves, and I decided to collect them. After three weeks, I obtained some adult flies.
Could you tell me more about them, please?

Several species of Pegomya make such mines on Chenopodium; from the photos it is hardly possible to tell which Pegomya is concerned.

Thanks a lot! :)

Is there any details needed for identification that could be photographed? I can take some more photos if needed.

Calyptrata specialists could advise you better. A study of a male specimen would be probably helpful, larval cephalopharyngeal skeleton can also provide some cues.
