Onycholyda rufofasciata
(Norton, 1869)
Onycholyda rufofasciata is a of in the Pamphiliidae, first described by Norton in 1869. The species is recorded from multiple Canadian provinces including Alberta, Manitoba, New Brunswick, and Newfoundland. As a member of Pamphiliidae, it likely produces webbing on plants during larval development, though specific biological details remain poorly documented. The Onycholyda contains approximately 20 species distributed primarily in the Holarctic region.

Identification
Distinguished from other Onycholyda by the combination of (reddish-) and fasciate (banded) coloration patterns implied by the specific epithet. may be separated from related in Pamphiliidae by antennal structure and characteristics typical of the genus. Positive identification requires examination of genitalic and comparison with .
Habitat
Associated with forested environments in and temperate regions of Canada. relationships are not definitively established for this , though related Onycholyda species feed on conifers including Pinaceae.
Distribution
Canada: recorded from Alberta, Manitoba, New Brunswick, and Newfoundland. The distribution appears restricted to northern North America, consistent with the transcontinental Canadian range pattern seen in several Pamphiliidae .
Ecological Role
As a , likely function as on , potentially contributing to in forest . webbing production by larvae may provide microhabitat for other small .
Human Relevance
No documented economic or medical significance. Not known to cause damage to commercially important forest resources.
