  • Hydroptiloidea

    microcaddisflies, purse-case caddisflies

    Hydroptiloidea is a superfamily of caddisflies (Trichoptera) containing the family Hydroptilidae. Members are distinguished by their minute size, rarely exceeding 5 mm, and the distinctive purse-shaped larval cases constructed only in the final instar. The group has a worldwide distribution and represents one of the most species-rich lineages within Trichoptera.

  • Ithytrichia

    Ithytrichia is a genus of microcaddisflies (family Hydroptilidae) established by Eaton in 1873. The genus contains at least two described species, I. aquila and I. bosniaca. Members of this genus are found in Europe and the Americas, with distribution records from Colombia, Denmark, Norway, and Sweden. Like other Hydroptilidae, these are small caddisflies with reduced wing venation.

  • Leucotrichiinae

    Leucotrichiinae is a subfamily of microcaddisflies (Hydroptilidae) in the order Trichoptera. The subfamily includes genera such as Betrichia and Mejicanotrichia, distributed primarily in the Neotropical region. Diagnostic characteristics involve features of the antennae, wing venation, and male genitalia. Larvae of at least some genera are dorsoventrally flattened with numerous broad setae and inhabit high-flow aquatic environments.

  • Metrichia

    Metrichia is a genus of microcaddisflies in the family Hydroptilidae, established by Ross in 1938. The genus belongs to the tribe Ochrotrichiini and is distributed across northern South America, with confirmed records from Colombia. As with other hydroptilids, adults are minute with reduced wing venation and larvae construct portable, silken cases.

  • Nothotrichia

    Nothotrichia is a genus of microcaddisflies in the family Hydroptilidae, established by Flint in 1967. The genus belongs to the subfamily Hydroptilinae and is characterized by distinctive morphological features that separate it from related genera. As with other Hydroptilidae, members are small-bodied caddisflies with reduced wing venation.

  • Ochrotrichia

    microcaddisfly

    Ochrotrichia is a large genus of microcaddisflies (family Hydroptilidae) comprising approximately 226 extant species, making it the most species-rich microcaddisfly genus in the Neotropics. The genus is predominantly distributed in the Nearctic and Neotropical regions, with one exceptional African record from the Democratic Republic of the Congo. Species are primarily found in freshwater stream habitats.

  • Ochrotrichiinae

    microcaddisflies

    Ochrotrichiinae is a subfamily of microcaddisflies within the family Hydroptilidae, comprising approximately 430 species across nine genera. The subfamily is most diverse in the Neotropics, with additional representation in the Nearctic and Australasian regions, including an endemic genus in New Caledonia. Phylogenetic analyses support its monophyly with the exclusion of Dibusa. The subfamily originated in the New World during the early Cretaceous, approximately 116 million years ago, with subsequent dispersal to Australasia via trans-Antarctic routes.

  • Orthotrichia

    microcaddisfly

    Orthotrichia is a genus of microcaddisflies (family Hydroptilidae) containing approximately 280 species worldwide, making it the most species-rich genus in the family. The genus exhibits hypermetamorphosis and has an almost worldwide but patchy distribution, with notable radiations in Australia (55 species, ~20% of global fauna) and China (14 species). Australian species are postulated to represent a relatively recent arrival from the Oriental Region, with morphological and biological differences from Northern Hemisphere congeners suggested to contribute to regional success.

  • Oxyethira

    Oxyethira is a genus of microcaddisflies (Trichoptera: Hydroptilidae) comprising over 200 described species worldwide. The genus exhibits high species diversity with new species continuing to be described, particularly from under-sampled regions. Larvae are aquatic and construct distinctive silk cases in their final instar.

  • Oxyethira forcipata

The species belongs to a genus characterized by reduced wing venation and small adult size typical of this family. Records indicate presence in North America within the Nearctic region. As with other Hydroptilidae, adults are likely associated with aquatic or riparian habitats where larval development occurs.

  • Oxyethira zeronia

    microcaddisfly

    Oxyethira zeronia is a species of microcaddisfly described by Ross in 1941. It belongs to the family Hydroptilidae, the largest family of caddisflies, whose members are characterized by their small size and reduced wing venation. The species is recorded from North America, though specific habitat and ecological details remain poorly documented.
