Onycholyda sitkensis
Onycholyda sitkensis is a of web-spinning in the Pamphiliidae, recorded from coastal Pacific Northwest regions including British Columbia and Alaska. Members of this construct silken webs on conifer foliage, within which larvae feed. The species appears to be rarely collected, with few documented observations.

Habitat
Associated with coniferous forests; larvae construct silken feeding webs on conifer needles.
Distribution
Known from southeastern Alaska (Sitka region) and coastal British Columbia, Canada.
Diet
Larvae feed on conifer foliage within protective silken webs; specific plant records for this are not documented.
Life Cycle
Complete with , larval, pupal, and stages. Larvae are web-forming feeders on conifer foliage; likely occurs in soil or leaf litter.
Behavior
Larvae are gregarious web-spinners, constructing communal silken shelters on conifer branches for protection while feeding.
Ecological Role
Herbivore in coniferous forest ; larval feeding may contribute to minor defoliation of trees.
Human Relevance
No documented economic or medical significance; rarely encountered due to limited distribution and cryptic larval habits.

Taxonomic note
The specific epithet 'sitkensis' refers to Sitka, Alaska, the type locality. The Onycholyda was historically treated as a subgenus of Acantholyda but is now recognized as distinct based on genitalic and larval characters.
