Carabus nemoralis (commonly called the "Bronze Carabid") is a ground beetle common in central and northern Europe, as well as Iceland and the island of Newfoundland. While native to Europe, it has been introduced to and is expanding its range throughout North America.
Carabus nemoralis is a beneficial predator as it eats the agricultural pest Deroceras reticulatum slug, in its young stage and also its eggs. Use of Carabus nemoralis as a biocontrol agent for multiple pests in large scale farming operations have been tested in recent years.
It is known that some Carabus nemoralis populations will regurgitate foul-smelling brownish-red liquid as a defensive mechanism.
