Here are some bugs I found waiting for the Hendricksons to pop this weekend on the Battenkill. I believe this first one to be Maccaffertium vicarium

Here's some others I haven't identified yet

I've got different angles on the Hendrickson Spinner, and the Brown Stone, as well as the Beetle- if they're needed. Also some more pics of different vicarium nymphs, some have a slightly different coloration.

Just on a quick glance:

The vicarium ID on the heptageniid nymph seems reasonable; the stonefly nymph looks like a perlodid; the (male) Hendrickson spinner ID seems right (though missing a tail); the big beetle looks like some sort of "borer," but I have no clue about the hitchhiker; the caddisfly larva is a hydropsychid; and I'd guess that the stonefly adult could be in Taeniopterygidae. (Dave could probably sort that out for you.)

Daytripper, I think the mystery larva is a predaceous diving beetle larva

Some Dytiscidae larvae have a superficial resemblance to some caddisfly larvae. If this larva had been photographed in the water (and from different angles), I think the differences would be easier to see.
