what do cicadas do
The Cicadoidea, cicadas (/sÉªËkÉËdÉ/ or /sÉªËkeÉªdÉ/), are a superfamily of insects in the order Hemiptera, suborder Auchenorrhyncha (formerly part of the obsolete Homoptera), along with smaller jumping bugs such as leafhoppers and froghoppers.hen the eggs hatch, the newly hatched nymphs drop to the ground and burrow. Cicadas live underground as nymphs for most of their lives at depths down to about 2.5 metres (10 ft). Nymphs have strong front legs for digging and excavating chambers in close proximity to roots where they feed on xylem sap.
