Stonefly shucks are a very common sight on the freestone streams I fish. But yesterday, they were a very uncommon sight. On the rocks lining a small side channel of the stream, there was a huge collection of recently abandoned golden stone shucks. I say recently because the shucks were on rock surfaces only inches from the stream surface, which means the hatch took place within the past few days.

But the remarkable thing was the split. Right down the middle of the wing case. And so obvious. I've never seen that before. Thought you all might enjoy it.

P.S. The details of the nymphs were so clear on these shucks and I was so intrigued by the splits that I forgot to turn over a couple to get pix of the underside. Maybe next trip, if I'm so lucky.
