Ditrysia

Epicallima formosella, a representative of the decaying wood moths.

Ditrysia is a taxon of butterflies (Lepidoptera ) from the subordination Glossata. It includes yet despite elimination of five superfamilies within the common taxon Heteroneura probably almost 99 % of all known species of butterfly. The remaining five superfamilies of Heteroneura are sometimes regarded as sister taxon with the name Monotrysia to Ditrysia. The monophyly of this is doubtful. Sure just seems that at least the Ditrysia and Tischerioidea form a monophyletic group.

Features

Although the group of Ditrysia is extremely rich in species, the species in their physique are quite similar, making it difficult to decode their relationship. By following autapomorphies the Ditrysia be distinguished: The Begattungsöffnung ( ostium bursae ) is separated as well as in the Exoporia of the locating hole ( Oviporus ). The Ditrysia the two are associated with each other. On the second sternum of the abdomen protruding Apodeme formed internally and the musculature of the proboscis is arranged in numerous short strips rather than long fibers.

A number of superfamilies, particularly the basal groups have showy, but plesiomorphic features that also occur in most taxa outside the Ditrysia. These are usually small moth, with an at least on the hind wings distinctly pronounced wing vein CuP. This feature, however, is in turn disappeared in some subtaxa. The caterpillars of this species develop in the interior of the plant and have circular or oval hooks arranged wreaths to the abdominal legs. Together with the taxa outside the Ditrysia this otherwise not more closely related to each other moths for practical reasons as small butterflies ( Microlepidoptera or " Micros " ) are referred to.

System

More recently, some subtaxa the Ditrysia were further segmented so that the taxon currently 33 superfamilies be attributed.
