Abstrakt: Feeding tests with thrushes (Hylocichlaspp.) led to the isolation of three novel steroid pyrones from fireflies (Photinus ignitusand P. marginellus) responsible, in part at least, for the unpalatability of these insects to the birds. The term lucibufaginis coined for these steroidal pyrones. The closest known relatives of lucibufagins are the familiar cardiotonic bufadienolides, found in certain toads and plants.
