Ergates faber (Linnaeus, 1767)

WORKSHOP: Mature larva

Ergates faber is one of the biggest beetles in Europa. It can reach the length of 60 mm (Length: 23-60 mm.)
Whole body is black-brown or reddish-brown. Head with large madibles. Antennae slightly overlapping elytral apex in male and middle part of elytra in female. Pronotum very transverse with slightly serrated lateral margins and with one lateral, postmedial tooth; disc with two smooth and shining elevations in male. Elytra finely granulated and punctured with two indistinct longitudinal costae. Apex of each elytron with a small, sharp, sutural spine.

Distribution. Central and South Europe, Caucasus, Turkey, North Africa

Biology The specie is closely related to dying wood, but it doesn’t blast living trees. The larvae develop in trunks, branches and occasionally roots of conifers (especially in Pinus and Picea). Larvae (see WORKSHOP) infest dead wood of greater diameter, moist stumps and roots, also in standing or fallen trunks. Life-cycle at least 3 years, with pupation in late spring and summer in the wood. The adults are active around sunset and can be found from late July until late September.

Lenght: 100 mm.
The larvae feed only for a short time under the bark, then burrow into the sapwood and often into the heartwood. When fully grown the larvae excavate their pupal cells close to the surface of the sapwood if it is a barkless tree. If the bark is present, they penetrate the inner layer of the bark so that only a very thin layer separates them from the exterior, and prepare an excavation for the pupal cell here.
