That's probably the shells of the exuvia (the old exo-skeleton that they moult before becoming adults) falling off the trees. Cicadas, like other insects, are basically too small to be injured from a fall.
That makes sense actually. Thanks for clearing that up, thought all cicadas are just terribly stupid.
They are not tiny lol
the shells are fun to play with
