Will there be a Mother's Day caddis hatch this year?

A few days ago I saw some moth-like little bugs flitting around beside the river. "Won't be long." I thought. All caddisfly hatches start like that. First you see a few, and then a few more, and after a week or 10 days, maybe two weeks later, you'll see lots of them. When they're on, you'll see them for a long time. The females return to the water several times over...
