Cerocoma is a Palearctic genus of blister beetle, whose biology is poorly known. As in other members of the family, these insects are hypermetamorphic. Larval hosts of few species were described. Imagines show distinct sexual dimorphism in the feeding apparatus and the antennae. All species in this genus have aposematic colouration. The antennae are 9-segmented, and the galea is modified into a sucking tube; imagines feed on pollen and nectar of Asteraceae and Apiaceae plants. The wings are well-developed, and the legs are long and slender.
