; order Hemiptera, suborder Homoptera)
Family of large homopterans in which the nymphs live underground, burrowing with the aid of crab-like fore legs, and feeding on the sap of roots. Adults live in trees, and the males produce a loud ‘song’. The life cycle may occupy several years and one well-known species in the USA spends 17 years underground. The nymphs of this species, like some others, construct ‘chimneys’ of earth above their burrows in which to complete the final moult. There are about 2000 species, occurring mainly in the tropics.
