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.
Short Lifespans. Killifish are among the aquarium fish with the shortest lifespan. They generally only live a year or two. Bettas are not far behind, averaging only about 2 years. There have been documented cases of Bettas living 5 years or more, but that is not the norm.
