“…It has been estimated that a few hundred thousand invertebrate species (insects, arachnids, crustaceans, worms) use surface-borne vibrations as a primary form of communication (Cocroft & Rodríguez, 2005 ; Hill, 2008 , 2009 , 2012 ; Virant-Doberlet & Čokl, 2004 ). Indeed, communication by surface-borne waves may also assist in courtship and mating, competition, localization of conspecifics, parental care, foraging, and danger perception (Caldwell, Johnston, McDaniel, & Warkentin, 2010 ; Castellanos & Barbosa, 2006 ; Cocroft, 1996 , 1998 , 1999 , 2001 ; Elias, Mason, & Hoy, 2004 ; Evans et al, 2009 ; Gogala, Čokl, Drašlar, & Blaževic, 1974 ; Hebets, Elias, Mason, Miller, & Stratton, 2008 ; Hill, 2001 , 2008 , 2009 , 2019 ; Hill et al, 2019 ; Hill & Wessel, 2016 ).…”
