Rhyncogonus caudatus Van Dyke

Tailed Rhyncogonus Weevil (Rhyncogonus caudatus)

This species is endemic to the island of Huahine, where it can be found on the leaves of several non-native and native plants, including nahe (Angiopteris evecta (G. Forst.) Hoffm.).

The animals are black in colour and bear some larger, white scales on the sides of the head, the body, and above all, the abdomen, where they build some kind of a short process.

The males reach a length of about 1,15 cm, the females, with 1,4 cm, are distinctly larger. [1]

Philodila astyanor (Boisduval)

Tahitian Hawk Moth (Philodila astyanor)

As far as I know, this species occurs exclusively on the island of Tahiti. It was originally described in the year 1875 from a single specimen (the one shown here), whose origin was not known resp. was wrongly (Mexico) labelled.

The species was redescribed again in 1990, it is a monotypic genus, that means it is a genus that contains only a single species.

The Tahitian Hawk Moth reaches a wingspan of about 7 to 8 cm.

~~~

There is a hybrid form of this species with the White-brow Hawk Moth (Gnathothlibus eras (Boisduval)), which had been described in the year 2002 as a distinct species (Papenoo Hawk Moth (Gnathothlibus collardi Haxaire)).

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.
