Heliobolus lugubris, also known commonly as the bushveld lizard, mourning racerunner, or the black and yellow sand lizard, is a species of lizard in the family Lacertidae. The species is found in Southern Africa: southern Angola, Namibia, Botswana, southwestern Zimbabwe, southern Mozambique, and south-central to northern South Africa. [1] [3]

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. [4]
