Bityla sericea is a species of moth in the family Noctuidae. This species is endemic to New Zealand. It is classified as "At Risk, Naturally Uncommon" by the New Zealand Department of Conservation.

Taxonomy

[edit]

This species was first described by Arthur Gardiner Butler in 1877 using a specimen obtained from John Enys and collected in the South Island.[1][2] George Hudson discussed and illustrated this species both in his 1898 book, New Zealand moths and butterflies (Macro-lepidoptera) and his 1928 publication The Butterflies and Moths of New Zealand.[3][4] In 1905 Hudson, thinking he was describing a new species, also gave the species the name Orthosia pallida.[5] George Francis Hampson, also mistakenly believing this was a separate species placed O. pallida in the genus Bityla.[6] Hudson discussed B. pallida in his 1928 publication.[4] John S. Dugdale synonymised B. pallida with B. sericea in 1988.[1] The holotype specimen of B. sericea is held at the Natural History Museum, London.[1]

Description

[edit]
Illustration of Bityla sericea by Edgar Albert Smith

Butler described the species as follows:

Primaries shining greyish brown, crossed by two widely separated and slightly diverging dusky lines, the inner one in the shape of a

, the outer one composed of small lunules with whitish exterior margins ; outer margin undulated, fringe silky whitish ; secondaries pale brown, fringe sandy whitish ; thorax greyish brown,' collar slightly darker ; abdomen ? : primaries below pale grey, costa and fringe whitish ; secondaries whitish, with a submarginal indistinct grey band, and the outer border, of the same tint, fringe whitish; pectus sandy yellowish, dusky in front ; legs sandy yellowish, banded with black. Expanse of wings 1 inch 6 lines.[2]}}

Although similar in appearance to Bityla defigurata, B. sericea can be distinguished from it as B. sericea has a pale fringe on its forewing.[7]

Distribution

[edit]

This species is endemic to New Zealand.[8][9] The species has been found in Wellington, Marlborough, North Canterbury, Mid Canterbury, Central Otago and at the Otago Lakes areas.[10] Hudson mentions the species was also collected in Thames[4] and in Napier.[5]

Behaviour and life cycle

[edit]

The adult moths are on the wing from February to May.[4] They are attracted to light.[3]

Host species and habitat

[edit]

The host of the larvae of B. sericea is unknown but they probably feed on Muehlenbeckia species.[10]

Conservation status

[edit]

This species has been classified as having the "At Risk, Naturally Uncommon" conservation status under the New Zealand Threat Classification System.[11]
