Copromorphidae


Copromorphidae, the "tropical fruitworm moths" is a family of insects in the lepidopteran order. These moths have broad, rounded forewings, and well-camouflaged scale patterns. Unlike Carposinidae the mouthparts include "labial palps" with the second rather than third segment the longest. With other unusual structural characteristics of the caterpillar and adult, it could represent the sister lineage of all other extant members of this superfamily. The genus Sisyroxena from Madagascar is also notable for its unusual venation and wing scale sockets.

Etymology

The word Copromorphidae derives from the Ancient Greek words wikt:copro- meaning "excrement" and wikt:μορφή meaning "shape" or "appearance", a reference to the visual characteristics of the moths' camouflage.

Distribution

These moths are widely distributed except the Palearctic region, occurring in Madagascar, India, South East Asia, New Guinea, Australia, New Zealand, the Neotropics, with limited temperate region coverage except that the genera Lotisma and Ellabella occur in North America, and the latter also in China. Over 20 belong to the genus Copromorpha occurring in Indo-Australia.

Behaviour

Adults are night-flying and attracted to lights. Caterpillars live between joined leaves, flowers or fruits or bore within stems, and some eat leaves. The larvae pupate with the silken gallery or descend to the ground and make a cocoon covered in detritus.

Larval hostplants

feed on the families Ericaceae, Moraceae and Berberidaceae. The anomalous genus Isonomeutis is a predator on "scale insects" on the Podocarpaceae species Dacrydium cupressinum.

Fossils

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.

Genera

The position of the enigmatic New Zealand genus Isonomeutis in this family in uncertain, as it lacks the flimsy cuticle of the pupa characteristic of other Copromorphoidea.
