[4][5] George Hudson followed Meyrick and discussed and illustrated this species under the name Carponsina eriphylla in his 1928 publication The Butterflies and Moths of New Zealand.

Legs dark fuscous, apex of joints whitish, posterior pair pale whitish-ochreous.

Forewings elongate, posteriorly slightly dilated, costa gently arched, apex obtuse, hindmargin straight, oblique; pale greenish, irregularly irrorated with white, especially towards hindmargin; about eight small black spots on costa, from which proceed obscure olive-green inwardly oblique strigulae; three inwardly oblique pairs of large tufts in disc, olive-green anteriorly, white posteriorly, margined above and below by small black spots, first near base, second at 1⁄3, third at 2⁄3; a short black streak on fold between second pair, crossed by a cloudy black mark margining them anteriorly; a slender white sinuate longitudinal line in disc between second and third pairs, unevenly black-margined, crossed by three or four irregular fine white strigae; a sub-terminal series of small fine irregular black marks, angulated in middle; hindmargin irregularly dotted with black scales : cilia whitish, towards base sprinkled with greenish.

eriphylla varies in the intensity of the green colouration on its forewings with some specimens being a yellowish-brown shade.

[8] Specimens of this moth have been collected near the Wellington Botanic Gardens and at the Ōrongorongo Valley,[9][10] as well as near Woodville in hill country.

[14][13] The larvae of this species feed on the callus tissue generated by their host trees as a result of damage caused by other insects including Aenetus virescens.

[8][6] The adult moths have been observed on the wing all year round but are most frequently seen from September to April.

[8] During the day the adult moths rest on tree trunks where their variable lichen mimicking colouration assists with their camouflage.
