Histeridae

(Family)

Histeridae is a family of beetles, commonly known as clown beetles or hister beetles. They have a distinctive appearance, with flattened leg segments recalling the baggy or flowing clothes of clowns or actors ("hister" is from the Latin histrio, actor). The 3,900 species of the family are found worldwide.

Characteristics

Clown beetles are small to medium sized. Two general body forms exist within the Histeridae. The more common form is nearly circular and very compact; the other form tends to be longer than wide and somewhat rectangular in shape. Many clown beetles are dark colored, often black, but they may have red, orange, or yellow markings. There are often grooves in the beetle's underside into which the antennae and legs can be retracted when the beetle feels threatened. Their legs are flat and widened, an adaptation for digging in soil or dung. Such an adaptation is said to be fossorial.

Systematics and Evolution

Histeridae belong to the superfamily Histeroidea, of the Staphyliniformia group. The family is currently divided into 330 genera and the following subfamilies:

  • Abraeinae
  • Chlamydopsinae
  • Dendrophilinae
  • Haeteriinae
  • Histerinae
  • Niponiinae
  • Onthophilinae
  • Saprininae
  • Tribalinae
  • Trypanaeinae
  • Trypeticinae

The relationships and (monophyly) of the subfamilies are not clear yet, and recent studies have cast much doubt on the traditional views[1].

Ecology

Clown beetles can usually be found living in dung, carrion, or animal burrows, where both the larvae and adults feed on the juvenile stages of other insects, especially those of flies. In this way clown beetles can be instrumental in controlling certain livestock pests that breed in dung. The Hetaeriinae and Chlamydopsinae subfamilies are myrmecophilic
