CicadaYear.com: cicadas
are between 2 and 5 cm (1 to 2 inches) long. Cicadas have prominent eyes set
wide apart on the sides of the head, short antennae protruding between or in
front of the eyes, and membranous front wings. Some cicadas produce sounds
louder than 100 dB! They modulate their noise by wiggling their abdomens toward
and away from the tree that they are on. Some species have 17 year life cycles,
e.g. the Magicicada, which is widespread in the USA.
