Ten-lined Scarab

The ten-lined June beetle is a scarab beetle common to western North America. The adults are commonly seen at lights, and often make a hissing sound when disturbed. The larvae are considered agricultural pests of a wide range of crops because they feed on plant roots which can weaken or kill the plants. If you look closely, you will notice the lines are not solid bands on the hard cuticle, but instead consist of thousands of small scale-like hairs.
