Estimation of dung beetle biomass (Coleoptera, Scarabaeoidea)

The length-to-body weight relation in specimens of 30 species of Scarabaeoidea coprophaga was calculated, to enable biomass to be estimated from information about body length. The relation proves as the literature predicts, to be a power function. When the species are grouped according to size and body shape, however, it seems that a linear relation may also provide good biomass predictions on the basis of length.
