Explanation of Names
Chrysobothris humilis Horn 1886
humilis = 'humble'
Rick Westcott says it is likely the male of Ch. humilis. This species exhibits one of the more extreme examples of sexual dichroism found in the Buprestidae. Males (black with red humeral patches) mimic models of the beetle subfamily Clytrinae, while females (metallic green) do not. This gender-specific dichroism is thought to be a result of spatial partitioning of the habitat, with males more active in conspicuous locations and thereby experiencing selective pressures that females are able to avoid (Hespenheide 1976). The species was described first from a female; the male was later described under another name, Ch. cupreohumeralis. --T.C. MacRae, 3.i.2008
