About this bug

A long, gray-and-black beetle with two large, eye-like spots on its thorax. When flipped over, it snaps a hinge on its body and launches itself into the air with an audible click.

You'll usually find eyed click beetles in woods and along trails and on trees and shrubs. They are most active in spring and summer.

Is it dangerous?

Eyed click beetles are harmless; the eyespots are a bluff to scare predators.

Our rating: Harmless, meaning it poses no real threat to people, pets or property.

When you'll see eyed click beetles

Eyed Click Beetles are most active in spring and summer. In spring, overwintering adults become active and many species lay their first eggs. Summer heat speeds up development, so populations can grow quickly.

Typical places to check: woods or trails and trees or shrubs.

About beetles

The eyed click beetle is one of the beetles. Beetles go through complete metamorphosis: egg, larva (grub), pupa and adult. The larval stage often does the most feeding and damage, and it can last from a few weeks to several years depending on the species. Adults protect their flight wings under hard wing covers called elytra, which is why most beetles look armored and meet in a neat line down the back.

Look closely at larvae as well as adults. Grubs in soil, fuzzy larvae in closets and small worms in flour are all beetle larvae, and finding them tells you where the problem is centered.

Should you get rid of it?

No control is needed. Eyed Click Beetles are not pests, and many help by eating other insects or pollinating plants. If one is indoors, move it outside with a cup and a sheet of paper.
