Quesada gigas is known from Texas (U.S.A.) (Sanborn & Phillips 2013). The genus Quesada, which includes just two species, has an extensive distribution in the New World extending from central Argentina to Texas. Quesada gigas the only representative of the tribe Hyantiini in North America north of Mexico. The remaining genera of the tribe are found in Central and South America.
Quesada gigas is the only Quesada species found in North America north of Mexico. This species may exhibit the greatest latitudinal gradient of any cicada. It appears to have a broad host range, which facilitates its use of a range of plant communities. In a single park in Brazil, the species was found to use members of 17 different families as hosts. In Argentina, Q. gigas has been found in the tropical cloud forests of the Yunga and tropical rainforests of the Paranense floristic provinces as well as in the temperate Chaco and Espinal floristic provinces. The species disappears in Argentina when potential host trees disappear from the floristic provinces. I
Quesada gigas are endothermic. Endothermy may help Q. gigas live in a greater variety of habitats. The species is associated with the vegetation of the southeastern coastal plain in Texas. The northern limit of the distribution extends to the grasslands in central Texas, similar to those found in Argentina.
