 "Acharia stimulea" (formally known as "Sibine stimulea") is a moth of the family Limacodidae that is most widely known and recognizable for its larvae phase.During the mid and late instar (a phase between two periods of molting in the development), "Acharia stimulea" exhibits its characteristic lime-green coloring along the top of the body that contains its most identifiable feature, a dark marking at the center that is inclosed in a white and black that resembles a saddle.The green of the body contrasts against its dark anterior (head ) and posterior (rear) which, along with the skirt of the body, contain tubercles with hollow spines that, when broken, release an irritating toxin into predators.
