Hierodoris electrica

Meyrick described the adults of this species as follows:

♀. 16–17mm. Head, palpi, thorax, and abdomen dark fuscous, slightly sprinkled with yellowish. Antennae and legs dark fuscous, posterior tibiae yellow-whitish. Forewings elongate, moderate, costa gently arched, apex rounded, hind-margin obliquely rounded; dark fuscous, strewn with ochreous-yellow hair-scales in irregular patches; a leaden-metallic line from 1⁄3 of costa to 2⁄5 of inner margin, angulated outwards in middle; a sinuate leaden-metallic line from above middle of disc to anal angle; a leaden-metallic line from middle of costa-obliquely outwards more than half across wing, thence curved round to touch a whitish dot on costa at 3⁄4, and continued in a strong curve near and parallel to costa and hindmargins to anal angle; space between first and second lines, and within first curve of third line, less strewn with yellow scales and therefore darker than rest of wing: cilia light grey, rather shining. Hindwings rather dark fuscous, somewhat bronzy; cilia light shining grey.

This species is endemic to New Zealand and has been found in the northern and southern areas of the South Island. However this species has not been collected in Buller, Westland, or Canterbury.

Adults of this species are on the wing from mid December until the end of February. This moth is day flying and has been seen on hot, sunny days. It was regarded by George Hudson as being rare and Robert Hoare states it appears to be rarer than its sister species H. s-fractum.
