15 Black Clock Beetle Facts You'll Never Forget

Black clock beetle facts are about their food, surroundings, and breeding habits.

The black clock beetle (Pterostichus madidus) is a small and attractive insect. While there is not a lot of information about them, they are primarily garden beetles that are most active at night. Their prominent features make them easily distinguishable from the usual variety of ground beetles since they have a shiny black exoskeleton with deep vertical ridges that are visible on the wing casings. In addition to this, their pronotum (prominent plate-like structure) is rounded and smooth with a central indented line in the middle. On most occasions, their legs are red-brown but can vary in hue depending on each individual.

This species of beetles is commonly found in the temperate regions of Europe, including in countries like Spain, France, the Netherlands, and Belgium. Pterostichus madidus are primarily found in open and shaded habitats under logs, barks, debris, dry moorland, as well as amongst grass. Adults are mostly flightless since they are better hunters on the ground and possess the qualities of quick colonizers. They can be classified as scavengers as well as predators due to their predatory nature towards arthropods. These beetles are also called clocks in Ireland. They get their name from their behavior and glossy black appearance.

This article covers information about the wings of a ground beetle, black clock beetle smell, and black clock beetle eggs.
