Gymnobathra flavidella

The forewings of this species measure between 4.5mm and 8.5mm in length. G.V. Hudson described the species as follows:

The expansion of the wings varies from slightly over 1/2 inch to nearly 3/4 inch. The fore-wings are bright yellow, with rosy brown markings; there is a minute mark on the costa at the base, a very indistinct costal edging and apical shading and three more or less distinct dark brown discal dots; a conspicuous triangular patch of rosy-brown is situated at the tornus, boarded towards the base with a blackish-brown line, which extends as a faint cloudy mark towards the costa. The hind-wings are white with the costal and terminal portions strongly clouded with pale rosy-brown. The cilia of all the wings are rosy-brown. In some specimens the fore-wings are more or less clouded with orange-brown and, as already indicated, there is considerable variation in size.

This species is found only in New Zealand. It is common in all areas of the North Island and in the top half of the South Island as far as Christchurch and Franz Josef.
