This process is called sublimation. The opposite (deposition) is where a gas turns directly into a solid. Sublimation occurs if the pressure and temperature are right for the specific substance, so that the solid phase in a phase diagram borders the gas phase.
Most cicadas go through a life cycle that lasts from two to five years. Some species have much longer life cycles, such as the North American genus, Magicicada, which has a number of distinct broods that go through either a 17-year or, in some parts of the world, a 13-year life cycle.

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.
