Leptoceroidea is a superfamily of caddisflies (order Trichoptera) established by Leach in 1815. It comprises of aquatic insects whose larvae construct portable cases from various materials. The superfamily is part of the suborder Integripalpia, characterized by larvae with fully sclerotized capsules and case-building .

Identification
distinguished from other Trichoptera superfamilies by wing venation and genitalic structures; larvae of Integripalpia (including Leptoceroidea) have fully sclerotized capsules and construct portable cases, unlike Annulipalpia larvae which build fixed retreats.

Habitat
Freshwater aquatic environments; larvae occur in streams, rivers, and other water bodies. Documented from Atlantic Forest streams in Southeast Brazil including montane regions with Dense Ombrophilous Forest and high-altitude grassland vegetation.
Distribution
Widespread globally; documented from Southeast Brazil (Serra do Caparaó mountain range between Minas Gerais and Espírito Santo states, Parque Nacional do Caparaó), with new records expanding known distributions in the Atlantic Forest biome.
Ecological Role
Larvae function as and collectors in freshwater , processing detritus and contributing to nutrient cycling in aquatic .
Human Relevance
Larvae are bioindicators of water quality; used in biomonitoring programs to assess stream health. occasionally attracted to light.
