Mopane worms

Gonimbrasia belina is a species of emperor moth which is native to the warmer parts of southern Africa. Its large edible caterpillar, known as the mophane worm, madora, amacimbi “pigeon moth” or masontja, feeds primarily but not exclusively on mophane tree leaves. Mophane worms are an important source of protein for many in the region. The species was first scientifically described by John O. Westwood in 1849. The mopane worm is so-called in English because it is usually found on the mopane tree, Colophospermum mopane. Other vernacular names for the caterpillars include:
