Ichneutica scutata
Ichneutica scutata is a moth of the family Noctuidae. It is endemic to New Zealand. This species can be found in the southern parts of the North Island as well as the eastern parts of the South Island. It is similar in appearance to I. insignis and I. skelloni but can be distinguished as I. scutata is much paler in appearance. It is likely this species inhabits lowland tussock grasslands as well as coastal dunes although it is not common in inland tussock grasslands. The larvae feed on a variety of herbaceous plants such as Plantago and Convolvulus species, Plagianthus divaricatus. It pupates on soil near its host plants. The adults are on the wing from late March to July.
Taxonomy
This species was described by Edward Meyrick in 1929 from a specimen collected by George Vernon Hudson in winter in Wellington. The male holotype is held at the Natural History Museum, London. In 1988 J. S. Dugdale placed this species within the Graphania genus. In 2019 Robert Hoare undertook a major review of New Zealand Noctuidae species. During this review the genus Ichneutica was greatly expanded and the genus Graphania was subsumed into that genus as a synonym. As a result of this review, this species is now known as ''Ichneutica scutata.''Description
Hudson described the grown larvae as follows:Meyrick described the adult male of the species as follows:
The wingspan of the adult male of this species is between 30 and 39 mm and the wingspan of the female is between 34 and 36.5 mm. Hoare has also assigned a small dark form of this species, found in Mid Canterbury, to this species on the basis of the similarities in the form of antennae, male genitalia and time on the wing. I. scutata is very similar in appearance to I. insignis and I. skelloni but can be distinguished as I. scutata is much paler and the forewing streak is reddish brown in colour in comparison to the black streak of the other two species.
