A living brooch, also known as a ma'kech, makech, and maquech, is a brooch made from a living beetle of the genus Zopherus, particularly Zopherus chilensis, which has been decorated with paste gemstones, bric-à-brac, and imitation gold and is tethered to a woman's blouse by a small chain. Such brooches have traditionally been made in the Yucatan Peninsula of Mexico as objects of personal adornment. They do not move quickly, are very hardy, and are capable of living for over a month without food or water.
