Hmmm...
This might be Hydropsyche/Ceratopsyche. The overall appearance and wing patterns of Rhyacophila and some hydropsychids can be very similar. Based on the resting posture, wing shape, and what I can make out of the tibia of the foreleg, I'm leaning toward this being a hydropsychid. When the maxillary palps can be seen clearly, distinguishing between them is easy: hydropsychids have a long thin 5th segment, and Rhyacophila has 4th and 5th segments are nearly equal in length. I'd be happy if someone would offer a third opinion here.

 
Hydropsyche
I'm inclined to agree with Mr. Gonzales. The picture doesn't show the details that are needed to properly differentiate the two families (Hydropsychidae and Rhyacophilidae) let alone the genera, but the two bold spots along the ridge line - the so-called windowpane effect - and the wing shape are both typical of many species of Hydropsyche. I've not seen that same combination in Rhyacophila. The antennae are also rather thin for Rhyacophila.

 
Hydropsyche
I agree with Bugei that this photo is of Hydropsyche not Rhyacophila

 
Thank-you! Where would you su
Thank-you! Where would you suggest I move this to? back to Caddis Flies?

 
Hydropsychidae...
would seem to be a fairly safe placement. Although your specimen is probably either Hydropsyche or Ceratopsyche, the only way I know to separate them in a photo such as this would be through a close inspection of the relationship of the Cu2 and A veins of the forewing. Unfortunately, those veins are in a spot that is seldom clear enough in most photos to draw that distinction.

Another unfortunate truth is that the vast majority of the Hydropsychidae photos will never be taken to genus let alone species, even though most of them probably belong to one of three very common genera: Hydropsyche, Ceratopsyche, or Cheumatopsyche. One can sometimes make a pretty good guess that will allow some of the Cheumatopsyche to be separated from the Hydropsyche/Ceratopsyche based mostly on size and color, but that's about as far as it can go most of the time.

 
Thanks I moved it to where yo
Thanks I moved it to where you said to. ^__^

Rhyacophilidae
Looks like Trichoptera: Rhyacophilidae: Rhyacophila.
