Eyed Hawk-moth Smerinthus ocellatus Wingspan 80mm. An aptly named moth with bold and striking ‘eye’ markings on the hindwings. These are exposed (as a deterrent to predators) only when moth is startled and hidden by the forewings when resting. Adult has marbled grey-brown forewings. Flies May–July. Larva is bright green with a pale diagonal stripe on each segment and a ‘horn’ at the tail end. Feeds on willows and apple. Common only in southern and central Britain.
