The name Chryptocephalus refers to how the head is concealed when the beetle is viewed dorsally. There are many species and many of them are very colorful and are very popular with collectors and photographers despite their small size. The immature stages lead secluded lives as grubs in the leaf litter, and each species may specialize in feeding on the dried leaves of one or a few species of woody plants. Oaks with new green foliage are usually a good place to observe adult beetles.
