[2] There are historical records of the cicada in Bexar County, Texas starting in 1934, but this population died out - possibly due to the extended drought of the 1950s.

Megatibicen dealbatus, commonly called the plains cicada, is a species of annual cicada. [1] Dealbatus is Latin for "whitewashed".. This species used to be called Tibicen dealbatus, but in July 2015, after genetic and physiological evaluation and reconfiguration of the genus Tibicen, this cicada and others in the genus Tibicen were moved to newly created genera.
Charles W. Holliday and Joseph R. Coelho devised a new key in 2004 to identify the Sphecius species, examining 4,451 wasps among the five New World species, and noting that 98% of the female S. convallis wasps examined had yellow markings on gastral tergites one to four (or fewer) and S. grandis had 98% yellow markings from tergites one to five ...

The life cycle of an annual cicada typically spans 2 to 5 years; they are "annual" only in the sense that members of the species reappear once a year. The name is used to distinguish them from periodical cicada species, which occur only in Eastern North America, are developmentally synchronized, and appear in great swarms every 13 or 17 years. [1]
Trillions of cicadas will appear throughout the US as two broods emerge simultaneously. The natural phenomenon only occurs every 221 years.
Cassini-type cicadas are especially common in the most southwestern populations and are the only 17-year cicada species found in Oklahoma and Texas. [7] Cassini-type cicadas are most often found in deciduous lowland woods and flood plains, rather than the upland woods favored by other Magicicada. [7]
