This aquatic insect was captured late yesterday afternoon. It was pretty much expired, but floating on the water's surface, perhaps 15 feet from shore, alongside a fishing pier on Lake Washington. It was 8 mm as measured from the front of its head to the end of its wings. Can you identify it by any of the following:

Hi zen leecher aka bill w-
It's a caddis for starters.
Yes, that it is.

Order: Tricoptera

As to the rest, is it possible we can get a clearer photo? How long are the antenna as compared to the wings? I have a couple of good guesses, but I cant quite make out how many spurs I am seeing on the front and middle tibia.

Hi plecoptera419-

I will take and post a photo if the fore and middle legs when I have time later today. As to the antennae, they were accidentally broken off a bit beyond where I cropped the photo, probably in the process of collecting. However, the would have been at least 2 1/2 times the length of the wings.

I like this game. Post pics. Please. I can guess and be wrong or...
Hi plecoptera419-





Well, it turns out that dissecting something so small under my stereo microscope without proper tools is a bit more difficult than anticipated. In any event, these are photos of what I believe to be a fore leg, and what I believe to be either a middle leg or a hind leg.

Ah yes. This I understand. Looking at bugs under a scope is not so easy on the eyes either.

So based on the original photo and the information I have, and without the specimen under a microscope, here is what I think we have:

The antenna being at least 2.5 times the length of the wings would indicate Leptoceridae. The scape of the antenna appears to be longer than the pedical. This specimen also appears to have a a two lines on either side of the mesoscutum. The maxilary palpi has five segments.

My second guess would be that we may have a female Limnephlidae. Does the specimen have an ocellus? It appears that may be the case, and based on the pics of the legs...hmmmn?

Blasted caddis are complicated!

Hi plecoptera419-

Good job. Leptoceridae is correct. The next step should somewhat easier.
Hint: focus on the forewing marking.

Ok so based on the forewing marking and further research,

Genus common name: ??? Long Horned Sedges
Genus taxonomic name: ??? Oecetis

I am also thinking this is most likely Oecitis Avara

Excellent work, plecoptera419. I also believe the genus to be Oecetis, and although I also concluded that O. ariva was likely, identifying caddisflies to species from a photo is tends to be speculative at best.
