Oxyethira zeronia
Ross, 1941
microcaddisfly
Oxyethira zeronia is a of microcaddisfly described by Ross in 1941. It belongs to the 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 and ecological details remain poorly documented.

Identification
Members of Oxyethira can be distinguished from other hydroptilid by reduced wing venation and specialized genital structures; specific diagnostic features for O. zeronia require examination of male genitalia. The is among the smallest caddisflies, with typically under 5 mm in body length.
Distribution
Recorded from North America, within the Nearctic biogeographic region. Specific locality data are sparse.
Life Cycle
As with other Trichoptera, development includes , larval, pupal, and stages. Larvae are aquatic and construct portable cases; specific case and developmental timing for this are undocumented.
Ecological Role
Larvae likely function as or gatherers in aquatic , processing detritus and contributing to nutrient cycling in freshwater systems.

Taxonomic note
The Oxyethira is diverse and taxonomically challenging, with many described based on subtle differences in male genitalia. O. zeronia was described by H.H. Ross in 1941 from North American material.
