Callidium aeneum (DeGeer, 1775)
|

|
The 9 to 15 mm large longhorn beetle Callidium aeneum (family Cerambycidae) is one of three species of the genus known to occur in Germany. Worldwide 21 Callidium species haven been described, the majority of them in the Nearctic. The silvicolous species lives in the montane and subalpine zone from North and Central Europe over Asia Minor and the Caucasus to Siberia. The development cycle takes one year in spruce, occasionally pine, fir or larch. The larvae need sufficient level of humidity to develop. Larvae present in processed timber wood can often finalize their development. Since pupation takes place in a sealed cell deeply embedded in the wood, Callidium aeneum can cause technical damage. In Germany the species is known from virtually all regions, but scattered and not common to rare. (CB)
