The larva has a yellow head spotted with red and its body colour is brownish grey with long lateral tufts on each somite. First somite is black and grey, other somites are grey. There are paired dorsal and lateral black spots on each somite, from which spring long black hairs. Spots on the thoracic somites are coalescing. Instead of usual coloured caterpillars, there are two morphs which can be found. Some larvae are blackish with a broad white dorsal stripe, the anterior tufts are reddish brown. The other morph is reddish with blue lateral spots. However, the cocoon is ochreous in all morphs with short black hairs projecting from it, which are intensely irritating.




Ecology


Larvae have been reared on Populus species and also feed on castor, jamun, pomegranate, rose, and sandalwood plants. The braconid wasp, Cotesia trabalae is a known parasitoid of the moth.
