The challenge of attracting and locating potential mates has driven the evolution of diverse mate-finding signaling systems. These systems can be complex, with multiple signals or signal components spread across different sensory modalities. When multiple modalities are combined in one communication system, features of each can be important to individual fitness; over evolutionary time, these can shape investment in different parts of a signal repertoire. One group of animals that commonly uses multiple signal modalities is Orthoptera. Cricket and katydid species within this order often produce airborne sound calls to advertise to potential mates. Many also produce substrate-borne vibrational signals. …
