Introduction

The subfamily Heliconiinae is composed of a diverse group of species distributed widely in the New and Old World tropics, and it also includes the largely Holarctic fritillaries (Argynnini). Many species in Heliconiini and Acraeini sequester and/or synthesize cyanogenic glucosides, which render them unpalatable to predators. As a result, they act as Müllerian mimics or models for palatable Batesian species in other groups.
