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.

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]
