Elateridae (click beetles) in the order Coleoptera (beetles)
Description

The eyed click beetle, or eyed elater, is common in the eastern part of our country. It lives in deciduous forests, where the larvae grow in decaying logs, preying on longhorn beetle grubs. The adults can be 1¾ inches long.

The eyespots on the pronotum make predators hesitate to attack. The click beetle’s real eyes are much smaller and positioned behind the antennae, on the insect’s true head.

Close relatives of this species live to the south and west of our state. Learn more about the eyed elater and other click beetles in their family page.
