Definition
Chimarra adamsae is a species of caddisfly belonging to the genus Chimarra in the family Philopotamidae, order Trichoptera.
Overview
Members of the genus Chimarra are commonly referred to as fingernet caddisflies. They are aquatic insects whose larvae construct silken nets to capture fine particulate organic matter from flowing water. C. adamsae was formally described in a taxonomic publication, adding to the diverse assemblage of Chimarra species that are distributed worldwide, particularly in tropical and subtropical regions. Detailed information on its ecology, behavior, and geographic range is limited in publicly available literature.
Etymology / Origin
The specific epithet adamsae is a Latinized genitive form typically used to honor a female individual bearing the surname Adams. The naming convention follows the International Code of Zoological Nomenclature, wherein the species is named after the person recognized for contributions to the field, collection of specimens, or support of the research.
Characteristics

Taxonomic placement:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Trichoptera
- Family: Philopotamidae
- Genus: Chimarra
- Species: C. adamsae
-
Morphology: As with other Chimarra species, adults possess slender bodies, elongated wings with characteristic venation, and long, hairy antennae. Males typically exhibit distinctive genitalia used for species identification. Larvae are adapted to lotic (flowing water) habitats, featuring a case‑like net structure used for filter feeding.
-
Life cycle: The species undergoes complete metamorphosis (egg → larva → pupa → adult). Larval stages are aquatic, while adults are terrestrial and usually short‑lived, focusing on reproduction.
-
Habitat: While specific habitat data for C. adamsae are not extensively documented, Chimarra larvae generally inhabit clean, well‑oxygenated streams and rivers with moderate to fast currents.
