在 Heliconiini 族的所有新热带属和热带 Cethosia 属中都证实了氰化作用。在所有含氰物质中，氰化物的来源是葡萄糖苷亚麻苦甙和莲花甙，前者的含量总是较多。蝎子本身生命周期的所有阶段都产生氰化物，其中卵子中氰化物浓度最高，雌性中氰化物浓度高于雄性。同位素实验表明，这 2 种氰基葡萄糖苷是由 Heliconius 在幼虫和成虫阶段由氨基酸缬氨酸和异亮氨酸合成的。氰基葡萄糖苷的分解代谢和合成代谢似乎都发生在蛹阶段。
Cyanogenesis was confirmed in all neo-tropical genera of the tribe Heliconiini and in the tropical genus Cethosia. In all cyanogenic species the source of cyanide is the glucosides linamarin and lotaustralin, the former always being present in the greater amount. All stages of the life cycle of Heliconius itself are cyanogenic, with the highest concentration of cyanide in ova and higher concentrations in females than in males. Experiments with isotopes have shown that the 2 cyanoglucosides are synthesized by Heliconius from the amino acids valine and isolencine at both larval and adult stages. Both catabolism and anabolism of cyanoglucosides seem to occur during the pupal stage.
