A predominantly black species. The head is almost entirely black in both sexes as is the thorax. The mesoscutellum and metascutellum are yellow. The stigma and venation are mostly brown, but paler in the male. The abdomen is also black but banded with reddish brown on tergites 4 to 5, or 4 to 6. The band is more orange-brown in the male.

Pamphilius hortorum larvae feed singly and form leaf rolls on raspberry plants.
