Glaucocharis microdora is a moth of the family Crambidae. It was first described by Edward Meyrick in 1905. It is endemic to New Zealand and is found in the southern parts of the North Island and the north and central parts of the South Island. It inhabits native forest at lowland to subalpine altitudes. The larvae of this species feeds on moss and adults are on the wing from November until February. It is similar in appearance to G. pyrsophanes but can be distinguished as G. microdora is of a smaller size and has bright yellow markings. It also lacks the broad white bars on forewings of G. pyrophanes.
This species was first described by Edward Meyrick in 1905 using two specimens, one of which he collected on Mount Arthur at 3000 ft in January, and was named Diptychophora microdora. George Hudson discussed and illustrated this species under that name in his 1928 book The butterflies and moths of New Zealand. In 1929 Alfred Philpott studied the male genitalia of this species. In 1971 David Edward Gaskin placed this species in the genus Pareromene. However in 1985 Gaskin recognised that Glaucocharis must take precedence over Pareromene and placed G. microdora into that genus. The female lectotype specimen, collected on Flora Saddle, Mount Arthur by Meyrick, is held at the Natural History Museum, London.
Hudson described the larvae of this species as follows:
Meyrick described this species as follows:
G. microdora is similar in appearance to G. pyrsophanes but can be distinguished is G. mircodora is of a smaller size and has bright yellow markings. G. microdora also lacks the broad white bars on the cilia of the fore-wings which are present on G. pyrsophanes specimens.
This species is endemic to New Zealand. G. microdora is found in the southern parts of the North Island to the north and central parts of the South Island. However Charle E. Clarke stated in 1933 he took specimens in the Lakes Manapouri and Te Anau area.
G. microdora inhabits native forest at lowland to subalpine altitudes. The larvae of this species feed on moss.
Adults of this species are on the wing from November to January.
