The Margined Blister Beetle is as black as ebony, but for a thin white line that runs down the middle of the elytra.
The Margined Blister Beetle can secrete a chemical called cantharidin when threatened. This secretion causes blisters to human skin and can injure an insect predator. This beetle feeds on plant tissue so contact with potential enemies is likely. It may be a garden pest in large numbers and handling individuals may best be avoided.
