Lappet moths

Trabala vishnou

Rose myrtle lappet moth

A freshly spun Rose myrtle lappet moth cocoon keeps stinging caterpillar hairs woven into its silk, so the pupa stays defended long after the hairs left living skin.

WhenJanuary to December

Males are apple green with a whitish disc on each forewing, while females are larger and yellowish green fading to ochre, with an enlarged, dark, scale dusted spot near the centre of each forewing.

Caterpillars feed on a very wide range of trees and shrubs, including rose, tea, guava and pomegranate, and carry dense tufts of hairs that irritate skin on contact and remain on the finished cocoon.
