Two major components in the "hairpencil" secretion of the male of the queen butterfly (Danaus gilippus berenice) have been identified. One, a crystalline ketone (2,3-dihydro-7-methyl-1H-pyrrolizin-1-one), is known from another danaid butterfly. The other, a viscous terpenoid alcohol (trans, trans-3,7-dimethyldeca-2,6-dien-1,10-diol), is new; its structure is confirmed by an unambiguous synthesis.
