Much like the different environments of a forest floor and treetops, interactions among insects vary within the much smaller-scale vertical zones of a turfgrass “canopy.” Researchers using clay models of caterpillars to lure predatory arthropods are revealing what a difference a few centimeters can make. Shown here is a schematic diagram of the experimental setup used in a new study by entomologists at the University of Georgia, in which clay models were placed at varying heights within a turfgrass environment.
