Taxonomy

This species was first described and illustrated by George Vernon Hudson in 1905 and was given the name Lythria fulva.[1] Hudson used a specimen collected at about 3500 ft at Wedderburn, Central Otago by J. H. Lewis.[3][2] Hudson discussed and illustrated this species in his 1928 book The Butterflies and Moths of New Zealand under the name Notoreas fulva.[4][2] In 1986 Robin C. Craw proposed placing this species within the genus Paranotoreas.[5] The lectotype specimen, collected at Wedderburn, is held at the Museum of New Zealand Te Papa Tongarewa.[2]

Description
Illustration by George Hudson.

Hudson described the species as follows:

The expansion of the wings is 3⁄4in. The fore wings are dull grey-ish brown, greenish-tinged. There is a wavy darker band near the base ; a broad median band with a strong rounded projection towards the terman above middle ; a dull greenish band on termen preceded by row of pale dots on veins, cilia grey with blackish bars. The hind wings are dull reddish-ochreous. There are three very obscure blackish transverse lines. The cilia are grey, faintly barred with darker.[3]

This species varies in depth of colouring on its fore and hind wings with some female specimens being extremely pale and having forewings that are coloured reddish-ochreous.[4]

Distribution

This species is endemic to New Zealand.[6] As well as the type locality, this species has also been found in Alexandra.[4] P. fulva also occurs in the Manorburn Ecological District,[7] as well as at Pisa Flats, Chapman Road Scientific Reserve, Springvale Junction, Moa Creek and other sites in Otago[8] and South Canterbury.[9]

Life cycle and behaviour
Observation of live P. fulva.

The adults of this species are day flying.[9] Adults have been recorded on the wing in March, October and December.[4][10] They are known to sunbath on the bare salt pan soil of their favoured habitat.[11]

Habitat and host species
Atriplex buchananii, larval host species of P. fulva.

This species occurs in the salt pans of Otago,[8][12] as well as at tussock grassland areas of montane South Canterbury.[9] This species has also been collected on glacial outwash terraces south of Tekapo.[13] Atriplex buchananii and Plantago coronopus have been recorded as the larval host plants of this species.[14] Larvae of P. fulva have been reared on Stellaria gracilenta and species in the genera Crepis and Hieracium.[14]

Conservation status

This moth is classified under the New Zealand Threat Classification system as being "At Risk, Relict".[15] This species is under threat as a result of loss of habitat upon which it relies.[9]
