  • Hydropsyche alhedra

    Hydropsyche alhedra is a species of caddisfly described by Ross in 1939. The species is currently recognized as a synonym of Ceratopsyche alhedra, reflecting taxonomic revisions that have moved this taxon to the genus Ceratopsyche. It belongs to the family Hydropsychidae, a group of net-spinning caddisflies known for constructing capture nets in flowing water.

  • Hydropsyche incommoda

    Hydropsyche incommoda is a species of net-spinning caddisfly in the family Hydropsychidae. Described by Hermann Hagen in 1861, this species is part of a large genus of aquatic insects whose larvae construct fixed capture nets in flowing water. Adults are nocturnal and attracted to light. The species is documented from North America.

  • Macronematinae

    net-spinning caddisflies

    Macronematinae is a subfamily of net-spinning caddisflies (Trichoptera: Hydropsychidae) established by Ulmer in 1905. Larvae construct silk webs to capture prey drifting in flowing water. The subfamily includes genera such as Macronema, Macrostemum, Leptonema, Leptopsyche, and the Neotropical endemic Centromacronema. Members occupy diverse freshwater habitats across multiple continents.

  • Trichoptera

    Caddisflies

    Caddisflies are an order of approximately 14,500 described species of insects with aquatic larvae and terrestrial adults. The order is divided into two principal suborders: Integripalpia, whose larvae construct portable protective cases while foraging, and Annulipalpia, whose larvae build fixed retreats and wait for food to arrive. Caddisflies are widely distributed globally and are recognized as important bioindicators of freshwater ecosystem health due to their sensitivity to water quality changes.
