butterfly

The wingspan of the moth is 82 to 92 millimeters. The forewings are long and narrow and have a bright orange color, which is somewhat paler and darker in the females. The apex is black. Sometimes a black stripe crosses the fore wing. This stripe can also be present only partially or completely absent. The hind wings are also colored orange and significantly smaller in relation to the forewings. The blackish wing edge is slightly wavy. The undersides of the wings are light brown to pale orange in color and have some weakly developed darker spots.

Egg, caterpillar, pupa

The egg is lemon yellow at first and later takes on an orange or brownish mottled color. The eggs are laid individually on leaves.

Adult caterpillars have a gray-pink to blackish basic color, from which a few light spots and an interrupted whitish side stripe stand out. They are equipped with long, strongly branched, dark thorns along their entire length. These cause skin irritation in humans after contact.

The doll is colored gray-brown and has small, silvery, shiny spots on the saddle. It is designed as a falling doll and imitates a dried up leaf ( mimesis ).
