Thanks for the IDs. I figured the Stonefly out, though it was a bit bigger and bulkier than what I've seen before. Do Dobsonflies pupate? Because that was my guess on the pale invertrbrate - that it would emerge from that as an adult.

For some reason I thought Dobsonflies were like Dragonflies and transformed the same way (the nymph climbs from the water onto vegetation and from it emerges the adult). But I guess not.
