Neophylax aniqua
Ross, 1947
Neophylax aniqua is a of caddisfly (order Trichoptera) first described by Ross in 1947. The species occurs in North America, with documented in southern Ontario and Vermont. Larvae inhabit cool headwater sections of streams and construct protective cases using silk and gathered materials. emerge in September and October following a summer prepupal .

Identification
Larvae of N. aniqua can be distinguished from sympatric Neophylax by their temporal development and position. They occur in the uppermost headwater sections of streams, with sequential downstream replacement by N. concinnus, N. oligius, and N. fuscus. Case construction materials and pupal case location differ from other Neophylax species, though specific distinguishing features for N. aniqua alone are not documented.
Habitat
Cool headwater sections of streams. Larvae occupy the uppermost stream reaches among the five studied Neophylax , with partitioning that places them sequentially upstream of .
Distribution
North America; documented in southern Ontario, Canada and Vermont, United States.
Seasonality
Larvae grow from late autumn through spring. emerge in September and October after a summer prepupal .
Diet
Grazes on and fine organic particles from exposed surfaces of rocks.
Life Cycle
Larvae develop from late autumn through spring. A summer prepupal precedes in September and October. The exhibits development with one per year.
Ecological Role
As a grazer on and fine organic particles, larvae contribute to nutrient cycling and energy transfer in headwater stream . Case-building activity may influence local substrate composition.
Similar Taxa
- Neophylax ornatusOverlaps in use in cool headwater sections, but differs in timing (June vs. September-October) and period (winter vs. summer)
- Neophylax concinnusOccurs sequentially downstream from N. aniqua in the same stream systems; larvae grow during the same late autumn through spring period but differ in temporal development and case construction
- Neophylax oligiusOccurs further downstream in the same stream systems; similar larval growth period but differs in position and temporal development
- Neophylax fuscusOccupies the most downstream among the five ; similar period (September-October) and summer , but differs in habitat position and temporal development

Family Classification Note
Sources differ in placement: Wikipedia lists Thremmatidae, while GBIF, iNaturalist, NCBI, and Catalogue of Life place N. aniqua in Uenoidae ( Thremmatinae). The latter classification is currently accepted in major taxonomic databases.
