It seemed like we had shown a ground beetle before, but maybe this is the first.

Ground beetles belong to the family Carabidae.

See those mandibles? Both adult and larval ground beetles are predators of other small animals including many garden pests. Because they help gardeners, ground beetles are considered to be beneficial insects.

This one was hiding under a piece of wood. Ground beetles often hide during the day and hunt at night.

Have you ever seen a ground beetle before?
