Some large Ephemerella mayfly nymphs cling to a log.  In the background, hundreds of Simuliidae black fly larvae swing in large clusters in the current.  In this picture: Mayfly Species Ephemerella subvaria (Hendrickson), Mayfly Species Ephemerella invaria (Sulphur Dun), and True Fly Family Simuliidae (Black Flies). From the Namekagon River in Wisconsin.

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.

I tried to photograph this salamander but it kept scurrying away from the camera.  The rocks in this little backwater are covered with a thin layer of very easily disturbed silt, so anywhere I followed it I didn't have much time to photograph before the water was too turbid for a good shot.  This is the best I got.  In this picture: Amphibian Order Caudata (Salamanders). From the East Branch of Trout Brook in New York.

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.
