see text Chrysina, or jewel scarabs (not to be confused with jewel beetles, which are a different family), is a genus of brightly colored, often metallic iridescent species of ruteline beetles.

They range from the southwestern edge of the United States, through Mexico and Central America, and as far south as Colombia and Ecuador.

Although the genus is wide-ranging, each species tends to be quite restricted in both habitat and distribution, with the vast majority only found in a single or two countries.

The majority of species have bright shiny green upperparts, but metallic silver and gold are also common colors (species with all-silver or all-golden upperparts only occur in Central and South America), and a few can be metallic reddish.

[7] Research has shown that the elytra of Chrysina are composed of about 70 chitinous layers of exoskeleton.
