Checkered Beetle - (Enoclerus rosmarus)

Authored By Staff Writer | Last Updated: 12/18/2013

The Checkered Beetle isn't interested in playing games. It is a voracious predator of insects that harm trees and plants.

A strong banding pattern on the elytra (wing covering) helped to name this beetle. Checkered beetles are colorful and easy to spot on tree trunks.

Both life stages are exceptionally good at eating insects like weevils, borer beetles and bark beetles. The adults feed on other species of adult beetle. They can be found resting on flowers, maybe even drinking the nectar while they are there. The Checkered Beetle larvae are immature, but still effective predators themselves. They follow the paths/tunnels of wood-borer beetle larvae, or bark beetle larvae, and eat them while they are still inside the tree trunk, putting a stop to the damage those larvae were inflicting on the tree.

They are likely to be seen around flowers and weeds from late spring to early summer.
