Agrilinae Catoxantha, Chrysaspis, Euchroma and Megaloxantha contain the largest species. The iridescence common to these beetles is not due to pigments in the exoskeleton, but instead is caused by structural coloration, in which microscopic texture in their cuticle selectively reflects specific frequencies of light in particular directions. Jewel beetles tend to be active on sunny days, especially in the heat of the afternoon.
