Abstract
Larvae of the specialized arctiid Tyria jacobaeae L. sequester pyrrolizidine alkaloids (PAs) from their major host plant Senecio jacobaea L. (Asteraceae). The PAs are transferred via pupae to adults as described years ago by Rothschild et al. (1979). Plants and insects containing PAs are usually avoided by predators. Larvae and imagines are aposematically coloured to advertize their unpalatability to potential insectivores.
