The bleach-old oaks night Bock ( Trichoferus pallidus ) is a threatened with extinction beetles from the family of longhorn beetles (Cerambycidae).

features

The body length of the beetle is 10 to 20 millimeters. The first part of the antennae reaches the front edge of the pronotum, the eyes are edged and roughly faceted. The third link in the antennae is simple. The pronotum is narrower than the wings , rounded on the sides and often structured with dorsal protrusions on top. The upper wings run parallel and are usually provided with a double puncture. The tarsi are bebürstet down and can fine longitudinal groove own. The beetles are reddish yellow in color and dense at the bottom, but pale yellow haired at the top. Behind the middle the elytra bear a brownish, sharply delimited drawing that is faded towards the back. This is lined with a longer and thicker hair to the front. The suture of the wing cover is also denser and lighter colored. The pronotum has an elongated bulge in front of the base.

distribution and habitat

The pale old oak night buck occurs in Central and Western Europe, in the Crimea and in the North Caucasus. The species' habitat is very old (dying) oaks. It is usually found on trees that are also infested by the great oak billy ( Cerambyx cerdo ) or nearby.
Trichoferus pallidus is considered an indicator of a species-rich beetle community and primeval forest relic species .

biology

It feeds almost monophag on old oaks. It is nocturnal, seeks light and is said to love warmth. The life cycle lasts two to three years.

Existence and endangerment

Trichoferus pallidus is threatened with extinction in Germany (Red List, Category 1). In Germany there are currently sites in Baden-Württemberg, Hesse, Rhineland-Palatinate and Saxony-Anhalt. The beetle was first found in 2004 in the forest near Lampertheim (South Hesse). Individual specimens were also seen there in 2008 and 2009.

Synonyms and systematics

As Erstbeschreiber had Guillaume-Antoine Olivier (1756-1814) these beetles in 1790 with the binomial name Callidium pallidum provided. Today it belongs to the genus Trichoferus Wollaston, 1854.

Further synonyms are known from the literature:

  • Hesperophanes pallidus
  • Callidium pallidus
  • Hesperoferus pallidus
