Dichaetomyia taveuniana Pont & Evenhuis

Taveuni House Fly (Dichaetomyia taveuniana)

The Taveuni House Fly was described in the year 2006, it was found during the sorting of insect trap material from the islands of Taveuni and Viti Levu.

It is a small, orange colored fly with a dark pattern on the dorsal side of the thorax.

~~~

The species belongs to a quite large genus, of which, however, only three species are known to occur on the Fijian Islands. Beside the new species these are the Elegant House Fly (Dichaetomyia elegans Malloch), which is known from the islands of Ovalau, Vanua Levu and Viti Levu, and the Orange House Fly (Dichaetomyia vicaria (Walker)), which is widely distributed, and which may not be native to the Fijian Islands.

Trupanea bidensicola Hardy & Delfinado

Beggarticks Fruit Fly (Trupanea bidensicola)

The Beggarticks Fruit Fly comes from the island of Kaua’i and was described in the year 1980.

It closely resembles the Thick-legged Fruit Fly (Trupanea crassipes (Thomson)) and was considered identical with it for some time.

The larvae of this species feed on the developing seeds of the Cosmosflower Beggarticks (Bidens cosmoides (A. Gray) Sherff), and probably also on other species from that genus.

Zizina otis ssp. labradus (Godart)

Lesser Grass Blue (Zizina otis ssp. labradus)

The Lesser Grass Blue, a very small, blue butterfly with a wingspan of only about 1,5 cm, is a widely distributed species, that is still expanding its range, so for example the species has reached the Hawaiian Islands by 2008.

The formerly recognized subspecies ssp. cheesmanae (Poulton & Riley), ssp. mangoensis (Butler) are now obviously included in the ssp. labradus (Godart), which occurs in the Polynesian region and beyond, however, the taxonomical position of this species and its subspecies varies from author to author.

The caterpillars feed on a wide variety of legume species.

~~~

In Niue the species is called pepe lanu moana mama.
