Cicadas are singing
the song of rain,
cooler days filled
with lush byways of
fruit and flowers.
The deafening roar
of these prehistoric looking
bugs, just before the rains
begin, is a symphony to our ears.

Cicadas are probably best known for their buzzing and clicking noises, which can be amplified by multitudes of insects into an overpowering hum. Males produce this species-specific noise with vibrating membranes on their abdomens. The sounds vary widely and some species are more musical than others. Though cicada noises may sound alike to humans, the insects use different calls to express alarm or attract mates.
