This species of Blister Beetle has a three-segmented body made up of mostly black with reddish-brown legs. Its 'knee caps' are black. The head is slightly larger than prothorax (shoulders), but abdomen is the longest part of the body. Antennae are relatively short and ridged. Wings fold back and appear as almost like an armor-plating that runs across the abdomen.
Adult Blister Beetles can be found on apple trees and other similar plants. The larvae are parasites to solitary bees like the Augochlora Sweat Bee. It will jump onto a passing bee, stowaway to the bee's lair and then feed on bee eggs and bee larvae that are there. After the beetle pupates, it makes its way out of the lair.
