Pamphilius gyllenhali  - Gyllenhaal's Spinner

Widely distributed north to Yorkshire, including south-west England and south Wales and with a separate cluster in the Scottish Highlands (Musgrove, 2022).

Mostly black with yellow markings. In the female, the head is black and flecked with variable yellow markings as is the thorax. The abdomen is largely black above but brownish around tergites 4 and 5 and the lateral margins marked narrowly with yellow.

In the male, the head is more markedly patterned with yellow. The thorax and abdomen above are not dissimilar to the female.

Pamphilius gyllenhali larvae feed singly in rolled leaves of sallow and willows. Goat Willow is preferred.
