The upperside forewings are marked in light and dark shades of brown and resemble the colouring of bark. The hindwings are pink coloured basally and then a yellow ochre. The hindwings are dominated by a large, blue, dark-centred and black-rimmed eyespot. The thorax has light brown sides and dark brown hairs in the middle. In addition to variations in the density of the forewing pattern intensity, differences in colour are also found on the hindwing. In f. ''flavescens'' Neumann hindwing pink is replaced by yellow in f. ''pallida'' Tutt by grey and in f. ''albescens'' Tutt. In f. ''rosea'' Bartel, the pink is deep and the forewings are yellowish brown; in f. ''ollivryi'' Oberthür, the ocellus is replaced by a buff brown patch. The adult moth has a wingspan of .

Historical description

Edward Newman described it thus:

The Eyed Hawk-Moth, so called from a large and beautiful spot in each of the hind wings that somewhat resembles an eye. The fore wings are brown, with a very beautiful reddish bloom over them, and clouded with olive-brown. The hind wings are of a delicate rosy red at the base, and a pale brown towards the margin; and each has a large and beautiful eye-like spot, grey in the centre, surrounded with blue, and the blue surrounded by a black ring. The skin of the caterpillar is rough, like

; it is pale green, sprinkled with white, and has seven oblique white stripes on each side. The horn at the tail is blue. It is very common in the autumn, feeding on apple trees in gardens, and on willow bushes in hedges. The chrysalis is red-brown, and glossy. The Moth is found about Midsummer.

Larva

The larva (caterpillar) is pale bluish or yellowish green with small white-tipped tubercules and a grey-blue tail horn. The sides are striped white or yellow and the spiracles are white ringed with dark red. The larvae grow to about 80 mm. The larval food plants are various species of ''

Pupa

The pupa is glossy reddish brown, and is formed below the soil surface in late summer, where it overwinters. The adults emerge the following summer in May or June.

Nomenclatural note

The name ''Smerinthus'' is apparently derived from the Greek feminine noun 'Merinthos', but has been Latinised with the masculine -us ending and is thus, according to the
