429 Yponomeuta irrorella
(Hübner, 1796)
Wingspan c. 22mm.A scarce and local species, occurring only in southern and south-eastern England, this species is identifiable by the patch of greyish suffusion in the centre of the forewing.
The larvae feed on spindle (Euonymus europaeus) in a silken web, but unlike some other Yponomeuta species, are not so gregarious.
Adults fly in July and August.
