Sorhagenia rhamniella (Zeller, 1839) Species

Last modified: March 6, 2021, 10:43 a.m.

A very rare species in Belgium, only observed in a few localities. For a certain identification, study of the genitalia is necessary, especially because of its resemblance with Sorhagenia janiszewskae, living on the same foodplants.
