Crepidophorus mutilatus is a beetle from the family of beetles (Elateridae).
features
The black nocturnal beetles are 11 to 18 millimeters long. The pronotum is parallel and much longer than it is wide, with the posterior corners having obtuse angles. The forehead is bent up like a bulge at the front end.
The species can be confused with other similarly sized click beetles, such as the forest humus snap beetle ( Ectinus aterrimus ). It can be distinguished by the shape of the pronotum and forehead.
distribution
Stanislav Laibner describes the species as central European in his book Elateridae of the Czech and Slovak Republics from 2000. It is also found in Northern Europe, but probably not in the British Isles.
Crepidophorus mutilatus requires heartwood from old trees and deadwood as a relic species . The larvae develop for at least three years in the silt of mainly deciduous trees and are aggressively predatory. The pupation takes place from March to May The short-lived adult beetles overwinter in the tree and do not become active until May or June. In the evening, beetles can occasionally be found in hollows in trees.
Danger
The International Union for Conservation of Nature and Natural Resources (IUCN) assesses the stock as potentially endangered ("Near Threatened"). The reason given is that the population of old trees in Europe is decreasing.
