This is a pretty clear photo of an Epeorus nymph clinging flat against a log. The big mound of debris on the bottom center of the picture, attached to the light rock, is a structure that's been puzzling me. I've found several in one section of the river. It's big, like 2 inches long and maybe 1/2-3/4 inch wide/tall, and hollow, like some sort of coccoon or something. It's clearly a structure built by some sort of little creature, but I'm not sure what.  In this picture: Mayfly Genus Epeorus (Little Maryatts). From the Namekagon River in Wisconsin.

These big bucket-like nets on the weeds are home to Hydropsychid caddisflies, as I verified by actually taking one apart to look at its inhabitant.  In this picture: Caddisfly Family Hydropsychidae. From Mystery Creek # 42 in Pennsylvania.
