I just searched the alderfly and I don't believe it's that. The alderfly almost looks like a stonefly, just shorter and more broad. Plus it seems thier eyes are not that large
That's why I was asking if these came from a warmwater river (or even a lake/pond). I have never seen a trout stream (coldwater) dwelling caddisfly with giant bugeyes like that. In that first picture, if that is the abdomen (hidden behind the underwing) with a long stinger-like (although probably a sex organ) appendage protruding... Then I'm pretty sure that it is not a caddisfly.
Likewise with fly #2... 100% positive that it's a freshly hatched dun... 100% positive that it's a female... about 75% sure that it's a Stenacron
(although the barring in the wings is more extensive than I'm used to seeing)... 0% sure on interpunctatum
(just my best guess).
My amateur entomology only extends as far as I need for fly-fishing in cold rivers and streams though... so if these insects came from warmwater, all bets are off.
