Carabus nemoralis (commonly called the "Bronze carabid") is a ground beetle common in central and northern Europe, as well as Iceland and Canada. While native to Europe, it has been introduced to and is expanding its range throughout North America.[1]

Ecology

Feeding habits

edit

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.[2]

Defensive adaptations

edit

It is known that some Carabus nemoralis populations will regurgitate foul-smelling brownish-red liquid as a defense mechanism.

Reproduction

edit

Carabus nemoralis typically has one breeding period in the spring with eggs hatching in autumn of the same year. [3])
