One afternoon I seined the San Juan River in Northern New Mexico to try and determine what the fish were rising to. My sein trapped a very odd insect (seen below) besides a lot of (expected) midges. I was surprised how well the images turned out because it was breezy that afternoon, but I'm afraid they may not be good enough to determine what this insect is. Here are a few shots of this "mystery" insect:

Looking at the above image, it has a rather short, stubby abdomen and thorax.

The second image shows that the wings are "tent-like" and are not similiar to a mayfly's wings nor that of a midge, whose wings lay flat along its body.
I showed this insect to a gentleman who was fishing close by and he said he had never seen anything like that. He also said he fished the SJR several times a year and had done so for years, but had never seen an insect such as this.
This insect was a lot larger than a midge and its wings were definitely not those of a mayfly, so I have no idea what this may have been. I have never seen a caddis on the river, so do not know if this body size would qualify as a caddis. The wings do not look like images I have seen of caddis's, but I could be wrong.
I wanted to get a profile view, but was unsuccessful. I have a few other photos, but I don't think they would be of any help.
Any help in solving this puzzle would be greatly appreciated. Thanks!
