“…That termites were using vibrational signals is not unexpected, because termites are small, herbivorous insects, and substrate-borne vibrational signals are very suitable for information gathering and communication in such animals. For example, substrateborne vibration signals communicate presence and attraction between group members, such as mothers and offspring or siblings, in many sucking bugs (Homoptera and Hemiptera), sawflies (Hymenoptera), and caterpillars (Lepidoptera) (Carne, 1962;Claridge, 1985;DeVries et al, 1993;Travassos and Pierce, 2000;Cocroft, 2001Cocroft, , 2005Č okl and Virant-Doberlet, 2003;Cocroft and Rodríguez, 2005), alarm and defence in sap-sucking bugs (Cocroft, 1996), and in caterpillars (Yack et al, 2001;Fletcher et al, 2006). Social Hymenoptera are also known to use substrate-borne vibration signals, particularly for foraging behaviours.…”
