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.
The Cicadoidea, cicadas (/sÉªËkÉËdÉ/ or /sÉªËkeÉªdÉ/), 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.he adult insect, known as an imago, is 2 to 5 centimetres (1â2 in) in total length in most species, although the largest, the empress cicada (Megapomponia imperatoria), has a head-body length of about 7 centimetres (2.8 in), and its wingspan is 18 to 20 centimetres (7â8 in).
