Blister beetles are found throughout the continental United States and the agricultural areas of Canada. Blister Beetles are soft-bodied , usually black or brown, mostly elongate and cylindrical beetles belonging to the family Meloidae.
Blister beetles are common insects found feeding on the flowers and foliage of various plants.
One group of blister beetles has body fluids that contain cantharadin, a substance that can cause the skin to blister, from which the family gets its name.
