Where Dung Beetles Perch Says a Lot About Community Evolution

Research on dung beetle behavior shows many species, especially smaller ones, choose a "sit and wait" strategy for finding food, while only larger ones actively search for food by following animals. A pair of biologists suggest this behavior is a resource-partitioning strategy to reduce competition for scarce food.

Can Cuticle Compounds Be Extracted From Insects Preserved in Ethanol?

Researchers studying hydrocarbons in insect cuticles typically avoid specimens preserved in ethanol, for fear the solvent may interfere with chemical analysis. A new study, however, finds ethanol has little effect—at least in the case of one wasp species tested—and opens the possibility that ethanol-preserved insects can indeed be used for the analysis of cuticular chemical compounds.
