Identification of the Ground Beetle

It’s understandable if you mix up ground beetles and cockroaches. Depending on the species, these bugs have diverse appearances. Dark brown or black are the most popular colors.

Other colors include iridescent green, metallic bronze, and speckled brown and black. Their shells can either be dull or lustrous. They all have three bodily components, notwithstanding their differences in size and color. On the sides, the thorax, and the abdomen, a small head with antennae and large eyes. These bugs don’t fly, but they make up for it by running extremely fast when disturbed.

The adults of the common ground beetle can grow to be 1/8 to 12 inches long, while the larvae are around 34 inches long. These larvae are black and segmented. Furthermore, they prey on small insects in the soil that may be beneficial to plant growth.


To develop, ground beetles go through a whole metamorphosis. The female bug produces a single generation per year by laying eggs in the ground. The pupa develops into an adult, which lives for one to four years.

The entire life cycle, from egg to adulthood, can be completed in a single season. Adult beetles are most visible between April and October, when they are most active.

These bugs eat aphids, caterpillars, slugs, snails, fly worms, and other soft-bodied insects. In addition, several varieties of beetles feed on plant pollen, seeds, and shoots. Some creatures may consume four times their body weight in food.

What is the cause of ground beetles?

Ground beetles are commonly found outside and do not cause structural harm. Some species, however, can produce a nasty gas or acid if they feel threatened. These bugs prefer to hunt for food at night, which may allow them to go undiscovered.

Insects like the ground beetle are attracted to lights. Bugs may enter your home through crevices, windows, or doors as a result of this. The good news is that most of these insects are incapable of reproducing indoors. This means that getting rid of the ground beetle from your home is simple.

What to Look For

Ground beetles hide in logs, rocks, and other moist areas, as previously indicated. They can also be found under mulch, leaves, wood chips, and pine straws, as their name suggests. These nests offer protection from the environment and predators, making them ideal for breeding.

Insects, on the other hand, seek better protection during heavy rain or high temperatures. This could entail relocating their hibernation places to domestic homes and structures. They can be found in basements or under objects on the floor inside homes.
