Melanotus americanus is a species of click beetle commonly found in North America. It is characterized by its elongated body, measuring around 1.5 to 2 centimeters in length, and its dark brown to black coloration. This insect is known for its ability to produce a clicking sound by snapping its thorax against its abdomen, which is used as a defense mechanism to startle predators. Melanotus americanus is primarily active during the night and feeds on plant material and decaying organic matter.
