I personally doubt that this otherwise Asian species occurs on the Island of Rapa, the Rapan plant is very probably a distinct, endemic species.

Hypena longfieldae Collenette

Longfield’s Snout Moth (Hypena longfieldae)

Longfield’s Snout Moth was described in 1928.

The species is endemic to central Polynesia and can be found on the Austral Islands, the Marquesas and the Society Islands, where it is obviously restricted to higher elevations.

The moth reaches a wingspan of nearly 3 cm, it is extremely variable. [1]

The species is split into several varieties, of which at least four occur within the Polynesian region, Geniostoma rupestre var. crassum (Cheeseman) Conn (endemic to New Zealand), Geniostoma rupestre var. glaberrimum (Benth.) Conn (most parts of Polynesia, especially French Polynesia), the nominate Geniostoma rupestre var. rupestre (western Polynesia), and Geniostoma rupestre var. tongense (A. C. Sm. & Stone) Conn (Fiji, Niue and Tonga).

Many of these varieties include synonyms that formerly were treated as distinct species. [1]

Ptychognathus easteranus Rathbun

Easter Island Crab (Ptychognathus easteranus)

The Easter Island Crab, described in the year 1907, was originally thought to be restricted to the waters around Easter Island, but was later found to occur on other Polynesian islands as well.

The species is restricted to estuaries and shallow stagnant waters, for example tide pools, but regularly enters freshwater streams and thus, is mentioned here.

The Screw Pine is a geographically widespread and exceptionally morphologically variable species (or maybe a species complex). In the Polynesian region this plant is found almost everywhere, except for climatically inappropriate areas like New Zealand or Rapa Nui.

The Screw Pine was once one of the most important plants for the Polynesians, and Screw Pine saplings, together with saplings of Breadfruit Trees, Coconut Palms, Taro and several others, were transported by the Polynesian settlers on their boats during inter-island migration – to be planted out at their new island homes.

The Polynesians, over time, reared numerous cultivars, among them such whose leaves are lacking spines on their margins, and which therefore are very well-suited for weaving.

The exceptional variability of the wild and cultivated forms lead to the description of countless species, subspecies and varieties. So, Harold St. John alone described in his “Revision of the Genus Pandanus” various female plants as distinct species – in many cases from geographically very localized populations. In a biological sense, all of these ‘species’ are part of the same population, and furthermore, it is impossible to designate male plants to such ‘species’.

Some of the morphologically distinct forms that are seemingly restricted to the higher elevations of larger islands, like Pandanus papenooensis H. St. John on Tahiti or Pandanus temehaniensis J. W. Moore on Ra’iatea, are often still referred to as distinct species.

(I personally, however, see all of these forms as Pandanus tectorius.)

Nevertheless, the genus is in urgent need of a proper revision!

~~~

As already mentioned, in virtually all parts of Polynesia the leaves were and are used for weaving, among other things, for elaborate mats, especially in Tonga, or boat sails (in former times on the Hawai’i Islands), right up to roofs and walls of houses (!). The stilt roots were used, for example, on the Cook Islands, for house building (as abutment walls) too.

The fruits are fruit heads comprising an aggregate of many tightly bunched phalanges or drupes that are edible. In some cultivars, these drupes reach the size of an apple. They are eaten especially in parts of Kiribati, Tokelau, and in Tuvalu.

Nesofregetta fuliginosa (Gmelin)

Polynesian Storm-Petrel (Nesofregetta fuliginosa)

This species is endemic to the tropical Pacific, where it breeds from parts of Melanesia (Vanuatu) well into East Polynesia, for example on the Gambier Islands in the Tuamotu Archipelago.

From the Cook Islands and on Rapa Nui, however, it is known only from subfossil remains.

The Polynesian Storm-Petrel is an about 25 cm large seabird, of which several color morphs are known to exist, which were formerly considered to represent distinct species. A remarkably dark morph (the Samoan Storm-Petrel) seems to be restricted to Samoa.

The bird is known in Polynesia by several different names, including kitai on the Marquesas, korue on Tahanea in the Tuamotu Archipelago, taio in Samoa, and te bwebwe ni marawa on the Phoenix Islands of Kiribati.

Utetheisa pulchelloides Hampson

Heliotrope Moth (Utetheisa pulchelloides)

This species occurs with several subspecies in many parts of the ‘Old World’ and has also colonized many island groups within the Indian – and the Pacific Ocean.

The subspecies occurring in Polynesia is Utetheisa pulchelloides ssp. marshallorum Rothschild (see photograph), it is found on the Fijian Islands, in Samoa and Tonga, in all parts of ‘French’ Polynesia up to the Pitcairn Islands.

The caterpillars of this species feed on the leaves of the beach heliotrope (Heliotropium foertherianum Diane & Hilger).

~~~

Another subspecies, Utetheisa pulchelloides ssp. vaga Jordan, regularly immigrates from Australia to New Zealand, where it has also already established temporary breeding colonies.
