The Erzfarbene channel beetle or Erzfarbige camel runners or ore channel beetle ( Amara aenea ) is a beetle from the family of ground beetles (Carabidae).
features
The beetles are 6.5 to 8.5 millimeters long and have an elliptical, elongated body. This is usually copper or greenish-metallic in color. There are also rarely black or blue specimens. The antennae also have this coloration, only the first three links are characteristically yellowish to reddish in color. The pronotum has right angles at the rear corners and connects almost perfectly to the wings . At the base you can see two impressions on each side. A fine scutellar stripe leads from the scutellum on both sides, parallel to the edge between the wings and the pronotum. The wings are very finely grooved lengthways. The thighs (femora) of the legs are significantly darker than the splints (tibiae).
Occurrence
The animals are found in the entire Palearctic , east to Lake Baikal , but are absent in the far north. They were introduced into North America . They are found predominantly in dry areas, such as meadows, dry grassland , fields and sandy areas, and less often in damp places, such as in forests or near bodies of water. They are widespread and very common.
Way of life
The diurnal beetles hunt small insects on the ground. But they also ingest parts of plants, particularly often they sit on ears of grain, from which they eat the grains. Otherwise they hide under stones or leaves on the ground. The larvae live in earth tubes in which they lurk for prey and also pupate after several moults. The adults hatch in autumn and overwinter.
