 Caterpillars feed on the families Ericaceae, Moraceae (Ficus) and Berberidaceae.The anomalous genus "Isonomeutis" is a predator on "scale insects" (Coccoidea; Margarodidae) (Dugdale et al., 1999) on the Podocarpaceae species "Dacrydium cupressinum".One fossil taxon is known, "Copromorpha fossilis" Jarzembowski, 1980 from the "Bembridge Marls" of Isle of Wight, a rock formation of Oligocene age, about 35 million years old (Jarzembowski, 1980).
