Megetra vittata

Megetra vittata is a species of blister beetle in the family Meloidae. It is found in North America. Like other blister beetles, megetra vittata excrete cantharidin, a toxic chemical, to defend itself from predators. Animals such as horses can fall ill and die from this toxin, as a result of eating many of these beetles, as they have been reported to get mixed in with their hay and other feed.
