Taxonomy

This species was first described by Edward Meyrick in 1885,[3] from a specimen given to him by Richard William Fereday.[4] Meyrick named the species Crambus sophronellus.[2][3] Meyrick gave a more detailed description of the species later that year.[4] In 1928 George Vernon Hudson also described and illustrated the species.[5] In 1975 David E. Gaskin placed the species in the genus Orocrambus.[6] Gaskin argues that Hudsons illustration in his 1928 book is actually of the species O. cyclopicus.[6] The type locality of the specimen is uncertain but is possibly Canterbury.[3] The type specimen is held at the Natural History Museum, London.[2]

Description

Meyrick described the species as follows:

Female. — 19 mm. Head and thorax ochreous-white, coarsely irrorated with greyish-fuscous. Palpi long, whitish, externally irrorated with grey. Antennae grey. Abdomen whitish, irrorated with grey. Legs grey-whitish. Forewings elongate, tolerably oblong, costa hardly arched, apex round-pointed, hindmargin straight, rather strongly oblique ; greyish-fuscous, densely irrorated with white, and with a few black scales : cilia whitish-grey mixed with white, base white. Hindwings light fuscous-grey, towards hindmargin darker ; cilia grey- whitish.[4]

Distribution

This species is endemic to New Zealand.[1][7] It has been recorded in Taparewa near Nelson,[5] the Mackenzie Basin,[8] and Central Otago.[6] It is possibly also present in Canterbury.[6]

Life cycle and behaviour

Adult moths have been recorded on wing in March.[6] The species is attracted to light.[5]

Habitat

O. sophronellus is thought to occur in short tussock grasslands.[9]

Host species

O. sophronellus is associated with Carex muelleri.[10]

Conservation status

This moth is classified under the New Zealand Threat Classification system as being Data Deficient.[11]

gollark: Yes. Vision was a great sense to start using.
gollark: I see.
gollark: We don't need it enough to pay that much though, it would take our octachorons at least 5fs to reverse SHA256 enough to get that.
gollark: We don't really need it.
gollark: LyricTech™ is quite seriously isomorphic to a finite simple group containing an octillion antineutrinos.
