The species is distributed throughout Central and South Europe, and the Caucasus, reaching the Transcaucasian region, and requires old well preserved broad-leaved forests growing in altitudes ranging from 0 to 800 metres above sea level. A paper dealing with larval nutrition and female oviposition preferences of some Necydalis species was written by Rejzek and Vlasák [❖]. More detail information about biology of Necydalis ulmi, You can find in Necydalis ulmi - habitat and biology page.
