Flashlight Anode Beetle

The Flashlight Anode Beetle is an airborne, night-only species of scarab beetle in Pikmin Z. It looks similar to the Anode Beetle but smaller and with the ability to fly around. It is completely harmless and can create a small amount of light from its abdomen. One Pikmin is enough to knock it out of the air and kill it.
