Imagines of these two species cannot be safely identified even by a genitalia check. However larvae are very different. Rearing experiments undertaken by Vladimir Savchuk (to whom I am grateful for his enthusiasm) proved that both species are present in our region (see the larvae photos at the bottom of this page). At two sites they appear sympatrically and synchronously. Probably both are equally common. More research concerning the species delimitation in our region is needed. The phenological information below concerns both species.
