Epichorista hemionana

Meyrick described this species as follows:

Male.—12+1⁄2-13+1⁄2 mm. Head, palpi, and thorax whitish-ochreous; palpi rather elongate, externally fuscous. Antenne whitish-ochreous, annulated with dark fuscous. Abdomen light grey. Legs grey-whitish, anterior and middle pair suffused with dark fuscous except at apex of joints. Forewings moderate, posteriorly somewhat dilated, costa rather strongly arched near base, thence nearly straight, hindmargin nearly straight, oblique; pale whitish-ochreous, with scattered obscure ochreous-fuscous strigule; base indistinctly suffused with ochreous-brownish; posterior 3⁄5, beyond a straight sharply-defined line from 2⁄5 of costa to slightly beyond middle of inner margin, fuscous, strigulated with dark reddish-fuscous, and becoming dark fuscous towards anterior edge, more broadly towards costa, and on a small very ill-defined costal spot towards apex: cilia whitish-ochreous or light brownish-ochreous, with a broad dark fuscous basal line. Hindwings grey; cilia grey-whitish, with a darker basal line. This species is noticeable as a result of the contrast between the pale basal and dark posterior areas.

This species is endemic to New Zealand. This species is found in the regions of Canterbury, Otago and Southland.

Larvae tie together the leaves of its host plants, species in the genus Acaena and other herbs. Adults are on the wing from January until April.
