Extract

During recent field studies of the behaviour and activiw of larvae in colonies of M. americanum and H. textor, it was noticed that nymphs and adults of Podisus placidus (Uhler) and of P. modestus (Dallas) frequently visited colonies of the eastern tent caterpillar and occasionally those of the spotless fall webworm. Although small larvae, particularly those of the tent caterpillar, fell prey to both nymphs and adults, larvae of the fifth and sixth instars occasionally exhibited special reactions.
