Taxonomy and etymology
editThis species was first described by Robert J. B. Hoare in 2010 from a specimen collected by John S. Dugdale at Mount Auckland in Auckland and named Izatha dasydisca.[1][2]
Description
editThe wingspan is 15–19 mm for males and about 26 mm for females.[2] I. dasydisca is visually very similar to I. austera.[2] However the male I. dasydisca can be distinguished by its mottled pale orange to reddish brown antennae.[2] I. dasydisca also has large forewing scale-tufts and its hindwing shape is smoothly rounded.[2] I. dasydisca has very dark hindwings which helps distinguish it from its near relative I. caustopa.[2]
Distribution
editThis species is endemic to New Zealand,[1] where it is only known from the northern half of the North Island in the Northland, Auckland and Gisborne areas.[2]
Biology and behaviour
editThe larvae have yet to be discovered.[2] Adults have been recorded on the wing in December, January and February.[2] The species has been collected by sweeping and by capturing when at rest on a tree trunk.[2] It appears this species is not attracted to light traps.[2]
Hosts and habitat
editThe host species of the larvae of I. dasydisca are unknown.[2] The adults of the species apparently prefers forest habitat as specimens have been collected in beech as well as podocarp forest.[2]
Conservation status
editThis species has been classified as having the "At Risk, Naturally Uncommon" conservation status under the New Zealand Threat Classification System.[3]
