reaching 22–28 mm, while the length of the forewings is 12–14 mm. The late generations are smaller and the

has an average of 16–26 mm. These moths are easily distinguishable from the mahogany or pink stripe, located on yellowish or cream background, crossing diagonally the dorsal sides of the upperwings from the posterior margin up to the apex. Discal spots are usually present and have the same colour as the postmedial line. The dorsal sides of the hindwings are whitish and unmarked. The fringes on the wings are mostly in the basic colour. The abdomen is pure white. Head and thorax are straw yellow. In males the antennae are bipectinated to three-fourths length. The hind tibiae bear two pairs of spurs. The intensity and the extent of the pink pigmentation is rather variable, depending on the seasonal temperature in the development of the pupae."Vestal"

Biology

Usually these moths rest with a tent-like posture on twigs and herbs, with the wings parallel to each other. They fly from April to October in the Northern Hemisphere. They are nocturnal, attracted to light and migrant. These moths breed in North Africa and in southern Europe, since they require constant warmth. The eggs are relatively long, yellowish, with distinct red spots. The caterpillars mimic twigs and therefore they are quite difficult to locate. They are slender and reach a length of about 25 millimetres. The basic colour is pale brown or green, with a whitish underside. The green forms usually show a dark brown or reddish irregular stripe on the back. The head is reddish brown and relatively small. These caterpillars feed on
