distribution

The longhorn beetle is widespread in Europe. It is only missing in Northern Europe, the British Isles , Denmark, the Baltic States and Scandinavia . In the east, the occurrence extends across Asia Minor and the Caucasus to the Middle East (Iran). It also extends further north via Siberia to Mongolia .

Way of life

The longhorn beetles can be seen from April to June. In Germany the species is on the red list in category 2 (endangered). A life cycle lasts 2 to 3 years. The species is polyphagous . The larvae develop in various deciduous trees, especially oak and field maple .

Taxonomy

The species was first described by Goeze as Cerambyx quercus . It is a type species of the genus Anisorus Mulsant , 1862. Today, following a revision by Eduard Vives, this is mostly understood as a subgenus of the genus Stenocorus .

The following synonyms can be found in the literature :

  • Cerambyx quercus Goeze , 1783
  • Toxotus quercus ( Goeze , 1783)
  • Anisorus quercus ( Goeze , 1783)
  • Leptura baja cabinet , 1798
  • Stenocorus dispar tank , 1797
  • Toxotus dispar ( tank , 1797)
  • Leptura humeralis Fabricius , 1787
  • Toxotus humeralis ( Fabricius , 1787)

There are at least two subspecies:

  • Stenocorus quercus aureopubens ( Pic , 1908). Widespread in the Caucasus and northeastern Turkey.
  • Stenocorus quercus quercus

The subspecies Stenochorus quercus punctipennis Reitter , 1914 suggested for finds from the Peloponnese (Greece) is mostly no longer recognized today.
