Description and Identification
They hatch in about three weeks from the eggs being laid. Initially, the larvae are dark brown with orange bands present on their bodies. As they grow older, they develop long brown hair on the side and shorter hair on the top. A mature larva measures 8cm on an average.
Pupation takes place in a cocoon amongst vegetation.
Sexual Dimorphism: Present. Males have reddish-brown wings while in the females it is of a pale gray coloration. Also, the females are slightly larger than males.
Color and Appearance
Forewing: When the wings are opened, a pair of narrow, light-yellow, and transverse bands are observed. When the wings are closed, the banded patterns remain the same.
Hindwing: When the wings are opened, they are either entirely reddish-brown (males) or pale gray (females). When the wings are closed, the reddish-brown or pale gray shades can hardly be seen.
Average wingspan: 4.8-7.2 cm
Flight pattern: Consistent
