Thread subject: Diptera.info :: Chironomini << Glyptotendipes ?

Hi everyone,

I found this female last summer. I think that Glyptotendipes could be a good option for her, and perhaps Glyptotendipes viridis.

Am I completely wrong?

It is not Glyptotendipes. Look at the shape of the pronotum, the plate between the head and the main part of the thorax. Species of Glyptotendipes have the pronotum deeply notched.

Thank you John!

Could it be a Chironomus then? I will try to keep on with the keys I have to see if I can go further.

Most Chironomus have "frontal tubercles", bumps above and between the antennae. Your fly does not. Females are hard to identify.

Thank you John, Chironomini then. I have some views of the tip of the abdomen both in ventral and lateral view if it can help.
