Adult Click Beetles are long skinny beetles with grooves running down their wing covers. Most adult Click Beetles are 12-30 mm long, a few species get up to 45 mm. The front of their heads and the back end of their wing covers are rounded. Unlike most beetles, the connection between the first and second section of the thorax is flexible, they can move their heads and first pair of legs separately from the rest of the body. This lets them do the trick that they are named for. They can snap the two sections, making a loud click sound, and flipping themselves over if they are lying on their backs.
Click Beetle larvae are long and shiny, with tough segmented bodies. They are sometimes called wireworms. Unlike mealworms (which are larvae of another family of beetles) click beetle mouth parts point straight forward.
Range length: 12.0 to 40.0 mm.
Other Physical Features: ectothermic ; bilateral symmetry
