Species: webbi

A desert-dwelling beetle in the Southwest and Mexico, the Black-and-white Click Beetle feeds on plants that can tolerate the arid, hot conditions. The long, slender beetle is mostly black, but its large, pronotum looks whitewashed with the black color peeking through down the middle. The wing coverings are also bordered with the same white color. Some beetles have less white coloring; some have more.

A surprising defensive behavior allows this beetle to escape predators. It uses a small spine to flick itself upward and away from danger. This same mechanism is also useful for flipping an upside down beetle back onto its feet. The snapping of the spine makes an audible clicking noise. Black-and-white Click Beetles are often found alone, wandering the ground between plants and trees.©BeetleIdentification.org
