Zygaenoidea

Definition

A superfamily of moths (Lepidoptera) characterized by aposematic coloration, often bright metallic patterns, and frequent association with cyanogenic host plants. The group includes burnet moths, forester moths, and related families, many of which are diurnal and exhibit Müllerian mimicry with other chemically defended insects.

Etymology

From Zygaena (type genus) + -oidea (superfamily suffix)

Example

The burnet moth Zygaena filipendulae, a member of Zygaenoidea, sequesters cyanogenic glycosides from its legume host plants and advertises its toxicity with red-and-black warning coloration.

Usage Notes

Zygaenoidea is one of several superfamilies within the Ditrysia, the largest clade of Lepidoptera. The superfamily is notable for high rates of larval sequestration of defensive compounds and convergent evolution of diurnal habits among otherwise nocturnal moths. Family composition has been refined by molecular phylogenetics; historically recognized families such as Heterogynidae and Somabrachyidae are now sometimes subsumed within broader groupings. The superfamily is distinguished from superficially similar groups (e.g., Arctiinae within Noctuoidea) by larval morphology, pupal structure, and molecular markers rather than adult appearance alone.
