Lanelater sallei
Lanelater sallei is a species of click beetle in the family Elateridae. The species has been used in biomechanical studies investigating the jumping mechanism of click beetles, which rely on a prosternal spine and mesosternal notch to produce an audible click that launches the beetle into the air. Studies using this species have supported hypotheses about the evolution and function of the clicking mechanism in elaterids.
