Hypolimnas bolina (L.)

Blue Moon Butterfly (Hypolimnas bolina)

The Blue Moon Butterfly, also known under the markedly ugly name Great Eggfly, was described in 1764.

The species has an exceptional wide area of distribution, which stretches from Madagascar over Asia and Australia into eastern Polynesia.

Three of the several subspecies occur within the Polynesian region, these are: Hypolimnas bolina ssp. otaheitae (Felder), which occurs on the Austral- and the Cook Islands, the Marquesas, the Society Islands, the Pitcairn Islands, and on Rapa Nui; Hypolimnas bolina ssp. pallescens (Butler), which is found in Fiji, in Tokelau, in Tonga, and in Samoa; Hypolimnas bolina ssp. rarik (Eschscholtz), which occurs in some parts of Kiribati as well as in Tuvalu. Another subspecies, Hypolimnas bolina ssp. nerina (Fabricius) is native to Australia and regularely visits New Zealand, but has not yet established a breeding population there, but probably will do so in time, and thus should be mentioned here too.

Males and females show a striking sexual dimorphism, males are always black with some white spots on the wings, which again are surrounded by a glossy dark blue ring. The females are much more variable in coloration, they furthermore produce several morphotypes, which, in appearance, often resemble other butterfly species, a phenomenon called mimicry.

The males are very territorial, while the females are wandering over wide ranges.

The larvae feed on plant species from the Acanthaceae, Amaranthaceae, Asteraceae, Malvaceae and the Urticaceae family.

In Niue this butterfly is called pepe mahina lanu.
