This species is widespread across Europe from France to south-eastern Europe; it is absent from much of the north and south (Bense 1995). In Hungary this species is widespread in the hilly and mountainous areas (O. Merkl pers. comm. 2009). In Romania it was reported from the hilly areas in Transylvania (P. Istrate pers. comm. 2009). It has also been reported from the European part of Turkey without giving exact locality (Althoff and Danilevsky 1997).

Habitat and Ecology
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.

Justification

European regional assessment: listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed overall large population, it occurs in several protected areas, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

In Hungary the population size and trend have not been quantified but it is quite rare (O. Merkl pers. comm. 2009). In Ukraine it is relatively rare.It is present in all German states, but for Mecklenburg-Vorpommern and Schleswig-Holstein there are only old records.

Major Threats
Habitat loss and fragmentation is occurring in some parts of the range as a result of urban encroachment and forest management (O. Merkl pers. comm. 2009). The major threat in Romania is the replacement of native oak forests with others species (P. Istrate pers. comm. 2009).
