The Vanessa indica is not reported as a pest on any crop but on ramie it is causing considerable damage by feeding on young tender leaves which affect the growth of the plant. The larvae of this insect pest feed on tender young leaves as shown in the picture. The adults lay the eggs on tender leaves in which larvae emerge and feeds on young tender leaves preferably at neck region of the leaves, due to this leaves look likes the hanging like position and latter get dry .The caterpillar feeds on young leaves and latter fold the leaves in such a way that both the margins get attached by silky web and pupation takes place inside the folded leaf. Latter the adult emerge as a beautiful Indian butterfly. The specimen of this insect pest was sent to NPIB, New Delhi for identification and determined it as Lepedopteron insect from family Nymphalidae of species Venessa indica Herbst. registered under RRS No. 3199-3202/11.This insect pest occurrence is a germplasm specific and infestation was found more on R- 67-34 (kanai) germplasm.
