Brachycentridae

Micrasema

Brachycentridae is a family of humpless casemaker caddisflies in the order Trichoptera. It is found in North America, Europe, and Asia. Georg Ulmer first described it in Germany in 1903 as a subfamily of Sericostomatidae.^[1] The type genus for Brachycentridae is Brachycentrus J. Curtis, 1834.^[2]

Distribution

The family Brachycentridae contains at least 100 species in about 8 genera. The genera Adicrophelps and Amiocentrus are found near the Arctic circle. Doliocentrus and Eorbachycentrus are found in southeastern Siberia and Japan and Western North America respectively.^[3]

Larvae

Most species' larvae make cases using plant or rock material. Several others make it out of silk. A few species' larvae in Brachycentrus form cases in the water with hairs sticking out to absorb food from the water.^[3]
