Orobophana musiva (Gould)

Mosaic Orobophana Snail (Orobophana musiva)

This species was described in 1847, it is found in Fiji, in Samoa, and obviously in Tuvalu as well.

The Mosaic Orobophana Snail is found under decaying vegetation at low elevations, very often near the coast.

It is a very small species, the shells reach heights of only about 0,2 cm, they vary in color from several shades of yellow and orange to reddish-brown.

Pacificagrion dolorosa Fraser

Sorrowful Damselfly (Pacificagrion dolorosa)

The Sorrowful Damselfly was described in the year 1953 on the basis of a male, that had been collected on the island of ‘Upolu, Samoa.

The species is almost unknown.

~~~

The Sorrowful Damselfly was not found during recent field studies, however, the exatct locality appears to be only insufficiently known. [2]

~~~

There obviously is at least one other, not yet described species on the island of Tutuila. [1][2]

Ostodes exasperatus Girardi

Large Ostodes Snail (Ostodes exasperatus)

This species was described in 1978.

The species is known from the islands of Savai’i and ‘Upolu, however, these two populations differ from each other in so far that the males from ‘Upolu are larger than the females, while the situation is reversed in Savai’i.

The shells reach a height of about 0,9 to 1,3 cm and a width of up to 1,3 cm. [1][2]

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.
