E. rosearia was first described by Edward Doubleday in 1843 and named Cidaria rosearia.[4][5]
Description
The eggs of this species are pale yellow and oval with a smooth shell.[6]
Alex Purdie describes the caterpillar of this species as:
Length, at rest, about three- quarters of an inch. Colour light-green, with indistinct whitish longitudinal lines, and a narrow median dorsal stripe of the ground colour, edged on each side by one of these whitish lines; a subdorsal whitish line on each side of the median stripe; the ground colour shows again as a lateral line, edged below with whitish. Under-side with delicate whitish or yellowish longitudinal tracings, as on the upper side. The junctions of the segments show yellowish or whitish rings when the larva contracts. Head, greenish-yellow. Body tapering somewhat to the head.[6]
The caterpillars form a chrysalis that is glossy and very dark brownish black.[6] They can be found amongst the leaves of the forest floor.[7]E. rosearia adults are varied in appearance. They can have a pinkish tinge or can be brownish in hue although olive green is also common.[7]
Distribution
E. rosearia are very common throughout New Zealand.[7]
