From the beetle family Elateridae, commonly called Click Beetles because its body has an unusual click mechanism when activated will produce a violent click which can bounce the beetle into the air. Its function is to escape from predators and also used for righting itself when it finds itself inadvertently on its back, due to its very short legs, without the clicking mechanism it would be difficult to right itself.
There is about 9300 species worldwide, so identifying which specific genus they are from would be challenging.
Click beetles have long, flat bodies and are masters of feigning death, where it can remain still for a long time pretending to be dead by merely touching it, which makes it an ideal subject for macro photography. They range in length from 1/4 in. to 4 in. Generally found in shades of black or brown, adults are usually nocturnal leaf-eaters.
