The Cicadoidea, cicadas, tonggeret, oer-oer, uir-uir are a super family of insects along with smaller jumping bugs such as leafhoppers and froghoppers. About 2,500 species of cicada have been described; many undescribed species remain.

The group of cicadas known as the tonggeret or oer-oer (uir-uir) are the loudest insect with a sound pressure level of 120 db, equal to jackhammer or car horn. The tonggeret are said to be noisiest in the late afternoon. A Wikipedia article on cicadas says that “’Cicada song’ is made by male cicadas with loud noisemakers called ‘timbals’ on the side of the abdominal base.”

Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They typically live in trees, feeding on sap, and laying their eggs in a slit in the bark. Most cicadas sing to avoid predators.

Cicadas have been featured in literature since the time of Homer's Iliad, and as motifs in art from the China. They have been used in myths and folklore to represent carefree living and immortality.
