Epiproct

from Wikipedia, the free encyclopedia

The unpaired dorsal plate of the eleventh segment of the abdomen of the insect is referred to as the epiproct (from ancient Greek έπί epi , German 'to, to, after' and ancient Greek πρωκτός prōktos , German 'after' ) . In most insects there is only a small remainder of this, which, together with the paraprocts, surrounds the anus and the end ring ( periproct ) formed from the telson , in many original insects all three plates (collectively referred to as anal valves ) are also very good educated.

Together with the paraproct, they assume a special function in the larvae of the dragonfly (Zygoptera). Here all three sclerites are extended to leaf-shaped tracheal gills and are used for breathing in the water.
