Pamphilius stramineipes - Highland Rose Spinner

A little known northern species. There was an extensive run of records between 1946 and 1952 from Speyside and Perthshire, then nothing until two further Perthshire records in 2010 and 2019 (Musgrove, 2022).

Female: The head is mostly black with yellow on the inner eye orbits, lower part of clypeus and a yellow stripe from the eye to the back of the head. The thorax is primarily black but with a yellow mesoscutellum and metascutellum. Abdomen mostly black above with lateral margins narrowly yellow. Apical tergites may be margined with pale yellow right across. Tergites 4 and 5 (sometimes others also) marked reddish-brown. Venation is basally yellow with yellow costa and subcosta and otherwise brown.

Male: The head anteriorly yellow along with genae and a yellow stripe from the eye to the back of the head. Mesoscutellum and metascutellum yellow. Abdomen mostly black above with tergites 4 and 5 (sometimes entirely) yellowish-brown. Venation as for female.

Pamphilius stramineipes larvae feed on rose leaves. Early instars feed in a roll of the leaf margin. Late instars draw several leaflets together or fold a leaflet.
