Detailed explanation-1: -A grasshopper’s eardrum, or tympanum, is located below. the second pair of wings on each side of the thorax. Locate the tympanum on your grasshopper using the. picture below. The tympanum is used for hearing.

Detailed explanation-2: -Specialized hearing organs, known as tympanal organs, have evolved in at least seven different orders of insects. Tympanal organs are usually defined by the presence of a tympanal membrane (or eardrum). They are backed by an air-filled space or cavity and are innervated by a chordotonal sensory organ.

Detailed explanation-3: -auditory organs of orthopterans, the tympanic organs on each side of the abdomen, are found in both sexes of grasshoppers and on the front tibiae of most crickets and katydids. There are auditory nerves running from special cells beneath a tympanic membrane (a thin area of cuticle, backed by an…

Detailed explanation-4: -In insects that possess them, tympanal hearing organs may mediate the detection of predators, prey, and potential mates and rivals. Unlike the ears of vertebrates, which are localized to cranial segments, the ears of insects may be found in a bewildering variety of locations on their bodies, depending on the species.
