''. ''Clytra laeviuscula'' has a special relationship with ants. The females wrap each egg with their hind legs in a ball of about 2 mm of excrements/feces and leaves it in the vicinity of an anthill. The eggs are taken to the nest by ants, where the larvae made a kind of tube that serves to protect them from ants. They feed on the waste and other detritus left by the ants, on their eggs and on their larvae. The adults usually emerge after about two weeks. The larval cycle lasts about two years.Mohr, K.H., in eds. Freude, H., Harde, K.W. & Lohse, G.A. (1966) Die kafer Mitteleuropas. 88. Familie: Chrysomelidae 9 95-299:119
