Scientific name: Setina irrorella
June to July. Rare. On a few sites in England, Wales and Scotland. Mainly coastal. Yellow, black-spotted, and medium-sized. Occurs on rocky coasts, shingle beaches and downland.
An unmistakeable moth due to its colouration and the configuration of markings. Can vary in colour from cream to yellow. Its name is suggested to have arisen from the moth’s habit of hanging from a blade of grass or leaf when at rest in the day, giving it a transparent appearance.
The adult males fly in the afternoon, at dusk, after dark and at dawn. The females are largely nocturnal. The ctaerpillars can be found from August to the following June before pupating in a flimsy cocoon between stones or rocks.
