Cerambyx nodulosus develops in living or moribund trees and can therefore be regarded as a physiological pest. Larvae expel large quantities of well visible sawdust which can serve as a hallmark to locate attacked trees. The adults are active during the day but are very difficult to find. In SE Bulgaria even very small, stunted Crataegus shrubs growing on sandy soils of the Black Sea coastal region serve as hosts of this remarkable insect.
Body length: 25 - 45 mm Life cycle: 3 - 4 years Adults in: May - August Host plant: polyphagous in fruit and ornamental trees or brushes (Prunus, Pyrus, Malus, Crataegus etc.) Distribution: South-East Europe, Turkey, Near East
The depicted beetles were collected in Primorsko (SE Bulgaria).
