Leaf-litter brood chambers in Dichotomius (Luederwaldtinia) Carbonarius (Mannerheim, 1829) (Coleoptera: Scarabaeidae): A novel behavior for dung beetles

Mostrar todas las versiones(2)

Dichotomius (Luederwaldtinia) carbonarius (Mannerheim, 1829) provisions its brood chambers entirely with comminuted leaf litter, mostly of fumo bravo (Solanum granuloso-leprosum Dunal), and covers them with a thin layer of entire or large fragments of leaves. This is the first recorded case of brood...
