Molorchus umbellatarum umbellatarum, a relatively common taxon with a large area of occurrence from the Atlantic coast to Iran,
has been described as Necydalis umbellatarum from Germany by Johann Christian Daniel Schreber in 1759 [▽].
Larvae develop first under the bark and later in the wood of dead thin twigs of various deciduous trees and shrubs.
The larvae overwinter in hook-shaped pupal cell in created in the wood, pupation in spring, life-cycle 2 years. Adults,
active from April to July (peak in May-June), are diurnal and anthophilous but can be also beaten from dying/dead twigs of the host plants.
