Cricket hearing organs
Crickets have auditory organs at the proximal ends of the fore-tibiae; the binaural sensory input enables orientation to a sound source and in response to sound, crickets turn towards the more intensely stimulated of their two ears. Among the many orders of insects, hearing is known to exist in only a few: Orthoptera (crickets, grasshoppers, katydids), Homoptera (cicadas), Heteroptera (bugs), Lepidoptera (butterflies and moths), and Diptera (flies).
