Mylabris quadripunctata, commonly known as the blister beetle, is a species of insect belonging to the family Meloidae. It is characterized by its elongated body, ranging in size from 10 to 20 millimeters. This beetle is easily recognizable by the four distinct black spots on its elytra. Blister beetles are known for their defensive mechanism of secreting a toxic substance called cantharidin, which can cause blistering and irritation on contact with human skin.
