These big caddisflies were tempting trout as they wriggled out of their shucks (Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.), while others skated across the water at a medium pace, probably egg-laying.
This caddisfly was collected from the West Branch of the Delaware River on May 15th, 2007 and added to Troutnut.com on May 18th, 2007.
This is the same caddisfly, moments after it emerged (the shuck is still attached a bit). You can see the body color was much lighter then.
This body almost cries out to be imitated with peacock herl, doesn't it?

I'm really just guessing. I'm too busy too key it out right now but I'd really like to know what it is. This was one of the main species the fish were taking (along with Apple Caddis) on the West Branch of the Delaware the other day.Replygenitalia pics?
