Miocalles superstes (Zimmerman)

Marotiri Miocalles Weevil (Miocalles superstes)

The Marotiri Miocalles Weevil was described in the year 1936 (as Microcryptorhynchus superstes Zimmerman).

This species is known only from the tiny Southeast Islet of the Marotiri group in the south of the Austral Archipelago, where the animals can be found on St.-John’s Beggarticks (Bidens saint-johniana Sherff) and on Yellow Purslane (Portulaca lutea Soland. ex G. Forst.), on which they obviously feed.

The flightless Marotiri Miocalles Weevil is only about 0,2 cm long, and reddish brown in color. [1]

Haloragis stokesii F. Br.

Haloragis stokesii

Distribution:

Austral Islands: Rapa

local names:

~~~

This species is endemic to the island of Rapa, a very similar but nevertheless distinct species is known from Rarotonga, Cook Islands.

There are several other forms, which may turn out to represent distinct species, Haloragis sp. ‘South Coast’ from Pitcairn Island and Haloragis sp. ‘Tahiti’ from Tahiti.

Misumenops rapaensis Berland

Austral Crab Spider (Misumenops rapaensis)

This species is obviously the only native species within the crab spider family, that is known to occur on the Austral Islands, where it is endemic to. As far as it is known, this species occurs on the islands of Rapa, Raivavae, Rurutu and Tubuai, where it can be found at all elevations and in nearly all suitable habitats.

Compared with other species of the family, the Austral Crab Spider isn’t much variable in coloration.

It is quite possible, that the several island populations represent distinct species, furthermore the placement of the species within the genus Misumenops seems to be doubtful.

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.
