Hypolimnas

Hypolimnas is a genus of tropical brush-footed butterflies commonly known as eggflies or diadems. The genus contains approximately 23 species, most of which are found in Africa, Asia, and Oceania. One species, the Danaid eggfly (H. misippus), is noted for its exceptionally wide distribution across five continents; it is the only Hypolimnas species found in the Americas.

Eggflies are known for their marked sexual dimorphism and Batesian mimicry of poisonous milkweed butterflies (Danainae). For example, the Danaid eggfly mimics Danaus chrysippus while the great eggfly (H. bolina) mimics the Australian crow (Euploea core). In each case, the eggfly mimics the danainid's markings, thus adopting the latter's distasteful reputation to predators without being poisonous itself.
