Trechus

Trechus austriacus

The Swift Runner ( Trechus ) are several hundred species one of the most species-rich genera of ground beetles. Trechus is probably a regression ( technical term ) " run " from ( gr ) trechein.

Dissemination

They are mainly in Europe, Asia and North America spread like islands in Southeast Asia, Australia ( there especially in the southern temperate zone)., Africa and the surrounding islands of the Continents Most species have relatively small distribution ranges ( endemism ) and are therefore faunistically of great interest. There are species that occur only on a single mountain top or on an island (eg BT laevipes on Monte Generoso or T. ochreatus on Zirbitzkogel in Austria ). In the Alps, about 80 species occur in Europe well over 200

Description

The typical feature of the genus is a bent-over on the wing-cover wing seam.

There are small, inconspicuous beetles with hidden life. Most Flink runner - types are kältepräferente, moisture- loving ( hygrophile ), flightless mountain dwellers. They can be in the leaf litter, find snow on the edges or stream banks, few in caves. A few species occur in caves and have stunted or no eyes.
