Rove Beetles : These beetles are typically dark brown or black with short elytra (wing covers) that expose their abdomen. They are often found in decaying organic matter.
Bark Beetles : These small, brown beetles bore into the bark of trees, causing significant damage.
To accurately identify a specific brown beetle, it's helpful to consider factors like size, shape, habitat, and any unique markings or behaviors. If you're dealing with a pest infestation, consulting with a pest control professional for proper identification and treatment is recommended.
