Oleander Hawk-moth (Daphnis nerii)
Oleander hawk-moth belongs to the hawk moth or Sphingidae family, widely distributed in Asia, Africa, and the Hawaiian Islands. They have been named so since the larvae of this species feed on the toxic oleander leaves to which they have attained immunity. Swedish zoologist and botanist Carl Linnaeus described it for the first time in his 10th edition of Systema Naturae, published in 1758.
Description and Identification
The new larvae are 0.3 – 0.4 cm long with a bright yellow body and long black horns at the rear end.
The older larvae’s color varies from green to brown, and they also adorn a large bluish-white eyespot close to the head alongside a yellow horn on the rear. A white band with blue and white dots can even be seen on one part of the body, along with black spiracles. They grow to about 7.5 – 8.5 cm in length. As they prepare for the pupal phase, the larvae eventually become brown.
Besides oleander leaves, the larva also consumes several dogbane species.
The pupa, 5.5 – 7.5 cm long, is light brown or reddish-brown, with black lines or spots running through the center. It mostly lies within the dry leaves or moss.
Sexual Dimorphism: Not recorded

Its other physical features include a green head with a reddish-brown patch in front and a grayish triangular band on top. The abdomen is olive green with black and tan lines intersecting the center, while it has a green thorax too.
