Mopane worms dry in the sun after being cleaned and boiled in salted water. The harvest of mopane worms (dried, they have three times the amount of protein as beef) is a major economic event in Botswana. Whole families move into the countryside and set up camp in order to collect the worms. While mopane worms are eaten in Botswana, they are a coveted form of protein in South Africa as well and have been largely over-harvested there. (page 126)
