Uenoidae

Definition

A family of stonecase caddisflies in the order Trichoptera, characterized by larvae that construct portable cases from sand grains and small stones. The family comprises approximately 7 genera and at least 80 described species, primarily distributed in the Holarctic region.

Etymology

Example

Larvae of Uenoidae, such as those in the genus Neophylax, differ from Limnephilidae in case architecture: uenoid cases are more cylindrical and tightly constructed, with mineral grains arranged in spiral or concentric patterns rather than the looser, irregular stone cases typical of many limnephilids.

Usage Notes

Uenoidae is one of several families historically grouped within the paraphyletic 'Limnephiloidea' assemblage; modern phylogenetic studies have supported its distinct family status. The family is most diverse in North America and eastern Asia. Identification to family requires examination of adult genitalia and larval case structure; the stonecase habit is shared with some Limnephilidae, so case morphology alone is not diagnostic.
