Mimicry

Juveniles of H. lugubris are black with light spots and move with a hunched gait, mimicking the appearance of Anthia ground beetles. This mimicry is thought to discourage predation, as the beetles spray formic acid as a defense mechanism and are thus less appealing targets for predators. This is one of very few recorded examples of a vertebrate mimicking an invertebrate.[3]
