Abstract Hydrogen cyanide, benzaldehyde and glucose have been identified as components of the larval defensive secretion in three species of leaf beetles, belonging to the genera Paropsis and Chrysophtharta . These substances, which at some stage may have been combined in the form of a glycoside, are apparently synthesized by the insects, rather than derived directly from the food plant.
