Cis forCicada

Cicadas are big, noisy insects that can be found all over the world. Most species are about 2-5cm long but some grow to 16cm long. Only male cicadas make the noise, and they are partly hollow to make the noise louder. Female cicadas are not hollow, and as they are very big and meaty, some people eat them. Cicadas spend the first part of their life underground as nymphs, a time of their life which can last for up to 17 years. When the nymphs come to the surface, they shed their skin and emerge as winged adult cicadas.
