Brachycentrus americanus (American Grannom) Caddisfly Larva Pictures

Classification

Kingdom Animalia (Animals)

» Phylum Arthropoda (Arthropods)

» Class Insecta (Insects)

» Order Trichoptera (Caddisflies)

» Family Brachycentridae (Apple Caddis and Grannoms)

» Genus Brachycentrus (Grannoms)

» Species americanus (American Grannom)

Both the genus ID (Merritt & Cummins) and species ID (Flint 1984) are pretty confident for this larva, a nice example of a common western caddisfly. It was by far the most abundant insect in my kicknet sample on this trip, and many of the rocks in the fast riffle where I sampled had dozens of these larvae clinging on.

This caddisfly was collected from the Dosewallips River on July 6th, 2020 and added to Troutnut.com on July 12th, 2020.
