If Oscars were awarded for Most Aesthetically Pleasing Sculpturing on an Insect, hister beetles would make the short list. Especially Hololepta, which not only shows the trademark histerid shininess but also has a flattened, paper-thin body. Michele Lanan, who collected this beetle for me, noted that it seems designed to inhabit the pages of a book.
In case it isn’t obvious from those killer mandibles, Hololepta is predatory. This one was found in a rotting cactus in the Arizona desert, where it likely hunted fly larvae.
