Description

Alaus oculatus

The click beetle has an elongated body that is entirely black and covered with tiny scales. It can reach a length of 1-1.8 in (25-45 mm). The pronotum (the dorsal plate of the prothorax) has, on each side, a large oval marking or eyespot made of darker scales with a white outline. That is how the click beetle gets its name. These ‘false eyes’ are a defensive adaptation against its predators by giving the impression of a bigger, formidable animal. Its real eyes are located on its head, behind the antennae. The striped elytra (wing case) are mottled with silvery, whitish scales.

Distribution: Central and North America.

FAQs

Q. Are eastern eyed click beetles dangerous?

Eastern eyed click beetles usually don’t bite and are considered harmless to people and pets. But if they are not handled carefully, they can give a sharp, non-poisonous bite with their strong mandibles. But their first reaction is to try flying away from danger. Biting is their last resort.

Q. Are eastern eyed click beetle good or bad?

Eastern eyed click beetles can be both good and bad. It is because, on the one hand, they consume agricultural plants in their larval stage leading to their labeling as pests. On the other hand, their larvae eat noxious wood-boring beetle larvae that are very harmful to trees. So they are both pests and beneficial insects.

Q. Are eastern eyed click beetles rare?

No, the eyed elater is pretty common in its range. It is neither rare nor endangered.
