click beetles, elaters
Elater is a genus of click beetles in the family Elateridae, characterized by a distinctive prosternal spine and mesosternal notch mechanism that produces an audible click when flexed. The genus includes species that are primarily nocturnal or crepuscular, with larvae that are predatory on other insects in decaying wood. Some species are attracted to fermenting substances and are captured in ethanol-baited traps.
