Abstract
Summary This study brings together several field observations as well as the data obtained from laboratory-raised Scantius aegyptius (Hemiptera, Pyrrhocoridae) a palearctic species close to Pyrrhocoris apterus. These observations show that these two species, although very similar in their external morphology, their bionomics and behavior, are separated by some differences. Some of these differences concern their geographic distribution and their ecological needs. Others more distinctive features lie in the structure of the phallus and the spermatheca; but the most remarkable difference concerns the ovarian physiology during the diapause; in fact, the ovaries of S. aegyptius, contrary to those of P. apterus, remain totally inactive during the winter diapauses.
