Epyaxa rosearia, the New Zealand looper or plantain moth,[1][2] is a moth of the family Geometridae. It is endemic to New Zealand.
Taxonomy
E. rosearia was first described by Edward Doubleday in 1843 and named Cidaria rosearia.[3][4]
Description
The eggs of this species are pale yellow and oval with a smooth shell.[5]
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.[5]
The caterpillars form a chrysalis that is glossy and very dark brownish black.[5] They can be found amongst the leaves of the forest floor.[6] 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.[6]
Distribution
E. rosearia are very common throughout New Zealand.[6]
Host species
While it is endemic to New Zealand,[7] the larvae have so far only been recorded feeding on exotic plant species: Nasturtium officinale, Plantago lanceolata, Trifolium ambiguum, Trifolium repens and Tropaeolum majus.[8] The larvae also seem to feed on the leaves of Trifolium caucasicum.
