Biology. Grasslands, forests, ruderal habitats. Adults occur in III–X. Oligophagous on Boraginaceae (Huber, Vayssieres 1990).
Notes. Taxonomy of the European and western Asian species of Pachycerus is not clearly understood (Meregalli & Fremuth 2013). According to Ter-Minasian (1988) and Meregalli & Fremuth (2013) all findings in European part of former USSR refer to P. cordiger (= P. segnis). So we consider all Ukrainian records as P. segnis (Germ.). Naturally, this is provisional concept serves here until revision of Palaearctic Pachycerus has been done. Łomnicky (1877: 152) identified this specie as Cleonus segnis Germ. (Faldermanni F.) ” and Cleonus faldermanni auct. nec Fåhraeus, 1842.
