Pamphilius albopictus - Ivory Spinner
This species was overlooked as British for a long time. Two specimens taken by Harwood near Aviemore in 1944 were previously determined as P. vafer, until Shinohara (1998) reidentified them during a review. A further specimen was photographed in Co Durham in 2021. The foodplant is very widespread in Britain especially in the north (Musgrove, 2022).
Males are unknown. Females are mottled black and ivory-yellow. Thorax is black with yellow and ivory mottling. Wing venation is mostly brown but the costa and subcosta are yellowish. Stigma is light brown. Added to the British list in 1998.
Pamphilius albopictus larvae feed singly on Bird Cherry leaves which are rolled downwards parallel to the mid-vein.
