Abstract
THE larvae of the warningly coloured tiger moth Arctia caja (L.) (Lepidoptera) and the grasshopper Zonocerus elegans (Thunberg) (Acridoidea) are polyphagous feeders with a predilection for poisonous food plants. These species can sequester and store various secondary plant substances such as cardiac glycosides and pyrrolizidine alkaloids1,2, which presumably function as predator deterrents. We report here that cannabinoids ingested with the leaves of Cannabis sativa L. are also stored by both insects.
