• Macrostemum

  Glossy Wing Sedges

  Macrostemum is a cosmopolitan genus of net-spinning caddisflies in the family Hydropsychidae, comprising at least 90 described species. Adults are recognized by distinctive dark and light contrasting wing patterns. Larvae construct silken retreats with capture nets to filter fine particulate organic matter from flowing water. The genus is particularly diverse in the Neotropical region, with species documented across Africa, Asia, Madagascar, and the Americas.
