Moved from Chironomini.

Moved

Moved from Chironominae. Now I'm leaning towards Chironomus.

Maybe Stictochironomus

This is likely Stichtochiromus. Another angle would help to see the relative positions of wing features.

It would be significantly smaller than half an inch -- more likely about 7 mm head to tail.

Thanks John. The size is really just a guess on my part, the picture was taken 9 months ago so I really don't remember. Anyway, I have added another photo, top down, hopefully that helps....

Looks like..

a midge of some kind and probably a female looking at the antennae. That's the best I can do until an expert comes along. Nice image!

Probably Chironomidae

The posture with the front legs held up is characteristic of Chironomidae. I think that plus the long first tarsomere indicates Chironominae but I'm not sure of that.

Thanks for the replies. I have added a closeup if that helps anyone narrow it down.

Diagnostic features

The diagnostic features for the most common subfamilies(1) are

1. length of first segment of tarsus (long in Chironominae, not long in Orthocladiinae, not sure about the rest)

2. crossveins in wing

3. branching of R vein

Yours is consistent with female Chironominae but that's not a firm ID. It clearly isn't Orthocladiinae.
