Scarabaeidae

(Scarab Beetles)

The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles.

Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between 1.5 and 160 millimetres. They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into a ball or fanned out like leaves to sense odours.

Many species are fossorial, with legs adapted for digging. In some groups males (and sometimes females) have prominent horns on the head and/or pronotum to fight over mates or resources.

Subfamily : Cetoniinae

Flower chafers are a group of scarab beetles comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit.

The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed.

Subfamily : Geotrupinae

These are commonly called earth-boring dung beetles or dor beetles. Most excavate burrows in which to lay their eggs. They are typically detritivores, provisioning their nests with leaf litter (often moldy), but are occasionally coprophagous, similar to dung beetles. The eggs are laid in or upon the provision mass and buried, and the developing larvae feed upon the provisions.

Subfamily : Scarabaeinae

The scarab beetle subfamily Scarabaeinae consists of species collectively called true dung beetles (there are also dung beetles in other subfamilies and families). Most of the beetles of this subfamily feed exclusively on dung. However, some may feed on decomposing matter including carrion, decaying fruits and fungi.
