This is an obligate saproxylic species. Polyphagous in broad-leaved trees (Acer, Alnus, Castanea, Fagus, Quercus, Ostrya, Corylus, Prunus, Ulmus, Juglans, Rosa, Malus, Pyrus, Vitis) and shrubs (vine Vitis, dog-rose Rosa). Larvae develop under the bark of dead twigs and branches. Life cycle takes two years, with pupation in spring, in the wood. Adults emerge in May - July, and are found on host- plants and feeding at flowers. In Hungary this species occurs in various deciduous forest types, mainly in thermophilous oak forests (O. Merkl pers. comm. 2009). In Romania it lives in in oak and beech forests (P. Istrate pers. comm. 2009). This species only appears in early spring when entomologists are mostly not out in the field, and hence it tends to be under-recorded.
