Research:

Acoustic communication of orthopteran insects: Crickets and katydids (Orthoptera, Ensifera) use sound signals. Males call by rubbing forewings together (stridulation) and both sexes may listen and respond: females approach calling males to mate; males may approach and fight. The calls encode information that affects how a caller is treated; generators and receivers (ears) show many interesting body forms that may be acoustic adaptations. My research is this bioacoustically related body design and its accompanying behaviour.
