Roeslerstammiidae

Overview

The larvae of Thereutis (6 spp.), Macarangela and Nematobela (3 spp.) first mine the leaves of their host plants; later instars feed fully exposed on the foliage; they pupate in a strong, white cocoon among leaf litter. The males of Amphithera heteroleuca have large eyes divided horizontally. The greyish white Thereutis have smaller, undivided eyes. Chalcoteuches phlogera , with metallic coppery green fore wings, recalls the Palaearctic and Oriental type genus Roeslerstammia . [Kyrki 1983; Moriuti 1978.]
