Abstract

Trox hamatus Robinson was observed feeding on an abandoned Canthon brood ball in southeastern Nebraska. Although some Aphodiinae and Scarabaeinae have been reported feeding on or stealing other scarabaeine dung balls, this represents the first reported observation of this behavior for a member of the Troginae. It is suggested that the brood ball was opportunistically used by the Trox, and the event is rare. In addition, new state records are provided for Trox aequalis Say, T. atrox LeConte, T. laticollis LeConte, and T. tesselatus (LeConte).
