Researchers at the University of Georgia are studying how clay models of caterpillars can attract predator insects and arthropods in turfgrass and reveal their presence by the marks they leave behind. Their latest study fine-tunes the method by evaluating the colors, shapes, and sizes of the decoys that work best. Shown here are clay models of different shapes and corresponding insects: (top left) Calosoma sayi beetle, (top middle) Tetracha carolina beetle, (top right) Agonum sp. beetle, and (bottom row) varying sizes of fall armyworm (Spodoptera frugiperda).
