Abstract The toxic amino acid β-cyano-L-alanine is shown to be present in 21 species of the Zygaenidae, which are known to produce and store the cyanoglucosides linamarin and lotaustralin. β-Cyano-alanine is also reported for the first time from other cyanogenic Lepidoptera, i.e. the Acraeinae and the Heliconiinae of the nymphalid family and from other species of the Nymphalidae, which have not been known to be cyanogenic before. Cyanogenesis, including the presence of β-cyano-alanine and the cyanoglucosides linamarin and lotaustralin is demonstrated for the first time for the Heterogynidae.
