The unassuming Dark Brown Click Beetle looks ordinary, but it has an extraordinary ability to flip itself upright with a simple flick.
Adult Dark Brown Click Beetles may wander indoors on hot days. This is usually when they are noticed. They are typically overlooked outside, where they are hard to see in foliage and ground cover. All Click Beetles have a spine on their ventral (belly) side that creates a violent snap that is strong enough to flip an upside-down beetle back onto its feet. The snapping creates a 'click' sound that is clearly audible. This flipping maneuver is useful to right itself should it fall over (i.e. climbing a rock). It can also propel the beetle away from dangerous predators trying to eat it.
The adult has a long, narrow, brown body. The elytra (wing coverings) are slightly ribbed and the insect is covered is short, downy hairs. Larvae of the Click Beetle are called wireworms because of their thin bodies. They are resemble mealworms, or centipedes without all the legs. Most wireworms feed on dead or decaying plant matter or animal tissue.
