C. pectinicornis has a wide distribution in the eastern Canada and United States, from Maine in the north-east to Alachua, Liberty and Santa Rosa counties in Florida to the south-east, and as far west as Kansas.

[1] C. pectinicornis was first described by Carl Linnaeus in his 1763 work Centuria Insectorum.

[2] Synonyms: Linnaeus 1763 Hemerobius pectinicornis, Hemerobius virginiensis, Semblis pectinicornis, Chauliodes virginiensis.

C. pectinicornis has a commensal relationship with Plecoptcracoluthus downesi larvae, which undergo their entire life cycle including pupation on the fishfly's mesothorax.
