Blister Beetles can secrete a chemical called cantharidin when they feel threatened. This chemical causes burns on both insect predators as well as human handlers. Contact can leave painful blisters that eventually heal on their own, but are meant to deter an animal from touching similar beetles in the future.

This species is black, and its red legs have black knee caps. Black and red coloring raises alarm when seen, as it is a popular combination in insects that can hurt. The smooth, satiny finish on its wing coverings may be tempting to pet, but it is best to let a Blister Beetle wander off. Adults can fly, but larvae cannot. Small beetle larvae are parasites of bees.

The Blister Beetle is typically 0.3 inches to 0.5 inches (9mm to 15mm) in size and has the following descriptors / identifiers: black; brown;red; small; winged; flying; blistering.
