Languria erythrocephalus Blatchley has been little known since it was described in 1924. Larval hosts are maidencane, Panicum hemitomon, a native southeastern range grass and to a lesser extent paragrass, P. purpurascens, an introduced pasture species. Immature stages of L. erythrocephalus are described and the habits, natural enemies, and damage are discussed. The most important of several parasites were a braconid, Heterospilus languriae Ashmead, and a eupelmid, Eupelmus cyaniceps Ashmead.
