Austramathes fortis

The adults tend to be on the wing in twilight hours but have also been known to be active during the late afternoon.

The distinguishing feature of this moth is the curved black line at the base of its forewing.

[3] In 1903 George Hudson, believing he was describing a new species, named it Miselia iota.

[1] The male holotype was collected by Mr Skellon in the Marlborough region and is held at the Natural History Museum, London.

[1] Hoare hypothesises that the latter form is likely to be more common as that colouration would assist the larva in camouflaging against the bark or base of its host plant.

[1] The distinguishing feature for this species is the curved black line at the base of the forewing.

[1] This behaviour may result in them not being collected as frequently via light trapping in the later evening hours.

[1] The larvae of this moth has been shown to feed on several Melicytus species including M. crassifolius, M. alpinus, M. macrophyllus and M.
