|Possibly a Nephrotoma?
Can this be narrowed down to the species level? It's the only photo I got.

|It could be Nephrotoma which has a yellow thorax with black markings, or orange-brown in North America. Tipulidae are notoriously difficult so you need to show a lot of detail, even then they are difficult and keys are needed.
There is an online key which may give you an idea but nothing more, go to #27.
If I had to make a best guess, I would go to 30A then 31B but that is assuming the thorax is opaque and not polished. The answer would be Nephrotoma tenuis, however I don't think the wing venation matches.
If I go to 30B, with a polished thorax, assuming the antennal flagellar segments are not bicolorous that would make it Nephrotoma ferruginea. That is more likely, look at the curved vein near the tip of the wing which joins at the stigma on the leading edge of the wing. I can't see the rest of the venation sufficiently to say for sure but from what I can see, it does look like it could be this species.
I'm pleased I took a proper look now, I thought it would be impossible as they often are!

|Thank you so much for the detailed reply. I tried going through the genus, but was not getting any where.
