What is "sphecius"

Cicada killer wasps (the genus Sphecius) are large, solitary, ground dwelling, predatory wasps. They are so named because they hunt cicadas and provision their nests with them, after stinging and paralyzing them. There are 21 species worldwide. The highest diversity occurs in the region between North Africa and Central Asia.

In North America, the term "cicada killer wasp" usually refers to the most well-known species, the Eastern cicada killer (S. speciosus). There are also a few other related genera sometimes referred to as "cicada killers", e.g. Liogorytes in South America and Exeirus in Australia.

The use of cicadas as prey is in keeping with the typical behavior of the tribe Gorytini, which tend to specialize on various members of the Cicadomorpha as prey items.
