Three big Ephemerella subvaria mayfly nymphs share a rock with some cased caddis larvae.  In this picture: Saddle-case Maker Genus Glossosoma (Little Brown Short-horned Sedges) and Mayfly Species Ephemerella subvaria (Hendrickson). From the Namekagon River in Wisconsin.

The white blotches on this rock are Leucotrichia caddisfly cases, and the wispy tubes are cases made by a type of midge.  In this picture: Mayfly Species Ephemerella invaria (Sulphur Dun), Caddisfly Species Leucotrichia pictipes (Ring Horn Microcaddis), and True Fly Family Chironomidae (Midges). From the Namekagon River in Wisconsin.

A variety of cased caddisfly larvae, probably mostly Neophylax, have clustered along the backside of a rock in fast water.  There seem to be some Helicopsychidae larvae clustered along the bottom, and a few other taxa are mixed in.  It's interesting that several larvae have especially large stones placed over the front openings of their cases, perhaps to block the case off for pupation.

It does seem to be the wrong time of year for Neophylax to be pupating, but that was the ID given for one of these which I collected and photographed up close.  In this picture: Caddisfly Genus Helicopsyche (Speckled Peters) and Caddisfly Genus Neophylax (Autumn Mottled Sedges). From Cayuta Creek in New York.

There's a stonefly nymph in the bottom right corner of this picture, but what's really interesting is those white blotches. They're pretty common in my Wisconsin home river river, stuck flat onto the rocks--lots of rocks have a speckled look as a result. They are microcaddis cases, made by larvae of the caddisfly family Hydroptilidae. These are made by larvae of the subfamily Leucotrichiinae, most likely the genus Leucotrichia. They spin little flat oval cases of silk tight and immobile against the rocks.  In this picture: Caddisfly Species Leucotrichia pictipes (Ring Horn Microcaddis). From the Namekagon River in Wisconsin.
