Vibrational communication and the ecology of group-living, herbivorous insects'

Abstract

Communication among members of a colony is a key feature of.the success of cusocial insects. The same may be true in other forms of insect sociality. I suggest that substrate-borne vibrational communication is important in the success of group-living, herbivorous insects. I examine three challenges encountered by herbivorous insects: locating and remaining in a group of conspecifics; locating food resources; and avoiding prédation. Studies of groups of immature treehoppers, savvHics and butterflies suggest that vibrational communication can be important in each of these contexts, enhancing the ability of these group-living herbivores to exploit the resources of their host plants.
