Lacon querceus (Hbst., 1784)
|
22 
|
The distribution of the Click beetle Lacon querceus (family Elateridae) stretches from the Pyrenees across Central Europe to Western Siberia. In Central Europe, the occurrences of the 9-12 mm large species are very insular and localized and the beetle is rare everywhere. In the mountains it rises to a maximum of 470 m above sea level. The development of the larvae takes place in rotten trunks and thick branches of standing oak infested with the mycelium of sulphur shelf (Laetiporus sulphureus). The larvae possibly prey on the larvae of Mycetophagus piceus. In late autumn the beetles hatch and hibernate in the puparium. In Germany Lacon querceus is confined to very few old oak forests and is regarded as critically endangered (RL 1). (KR/CB)
