Tymbal
- Body of male Cicada from below, showing cover-plates of sound-producing organs
- From above showing tymbals (drums), natural size
- Section showing muscles which vibrate tymbals (magnified)
- A tymbal at rest
- A tymbal thrown into vibration (as when cicada is singing), more highly magnified
The tymbal (or timbal) is the corrugated
tiger moths, the tymbals are modified regions of the thorax and produce high-frequency clicks. In lesser wax moths the left and right tymbals emit high-frequency pulses that are used as mating calls.[1]
The paired tymbals of a cicada are located on the sides of the
dB (SPL), among the loudest of all insect-produced sounds.[2]
They modulate their noise by positioning their abdomens toward or away from the substrate.
The tymbals of a tiger moth are specialized regions on the
"jam" the sonar of moth-eating bats.[6]
