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.
