Wings usually well-developed and most species are strong fliers, many chafers fly with the elytra closed. Females lay their eggs in rotting wood above ground. of Onthophagus are often metallic to some extent, while chafers tend to be more gaudy, brightly coloured and metallic, tropical species more especially so, although nocturnal species e.g. Creamy white to yellow with a dark, well-sclerotized head. Three, basic strategies are seen in dung beetles; those that collect dung, mould it, remove it from the source material and bury it so avoiding competition and desiccation e.g. The life cycle of many species is broadly similar with eggs deposited in organic host material or in the ground nearby, these hatch quickly and produce characteristic C-shaped larvae which develop quickly, although in many chafers this is prolonged over several seasons, passing through a small number of instars, often only two, and pupating in the ground or in a cell among the host material. as necessary. As a substitute, here is a collection of photographs of specimens from Lech Borowiec's website. This non-native species is now widespread in Britain and Ireland. Because the family is so very diverse the above discussion has been necessarily brief and superficial but detailed information can be found by following the subfamily links, and some of the variation in the details of the classification will be discussed.

Dynastinae in particular, but dung beetles in general, are also fascinating for their sexual dimorphism which may be extreme and is usually the result of sexual selection. Frontoclypeal suture present, labrum variable from rounded to deeply emarginate. Such effects include slowing beetle larvae development, reducing the size attained at adulthood and reduced breeding capacity. The larvae of most scarab beetles are whitish, C-shaped grubs that live underground or in other protected places. etc. However, instead of laying their eggs in rotting wood underground, they use wood and tree stumps above the ground. Though we are uncertain of the exact species, we suspect it might be the larva of a Green June Beetle, Cotinis nitida, which you can find pictured on BugGuide. Damage can be especially serious when the white grubs feed on young plants. The Geotrupidae, Trogidae and Glaphyridae were formerly included as subfamilies. Includes chafers with unequal meta-tarsal claws. Many species are generalists and will be found in the dung of a range of herbivores but many are specialists, occurring only in e.g. Magpies eat large quantities of scarab beetles and grubs when they find them. The vast majority are generally known as dung beetles or chafers , terms which tend to conceal their amazing diversity, but the group also includes the Dynastinae MacLeay, 1819, the so-called Rhinoceros and Hercules beetles etc. Species vary widely in size from less than 2mm to about 160mm, many are massive as well as large and many males appear much larger due to exaggerated cephalic and pronotal development. Those developing in avian and mammal nests occur throughout the world, many are generalists e.g. They are black beetles, some species with paler elytra, and dig vertical burrows beneath dung. Includes the chafers Hoplia philanthus (Füessly, 1775), Serica brunnea (Linnaeus, 1758), Omaloplia ruricola (Fabricius, 1775) and 2 species each of Amphimallon Latreille, 1825 and Melolontha Fabricius, 1775 as well as the occasionally recorded Polyphylla fullo (Linnaeus, 1758) which has never been established.

The larvae are called grubs, they do not like sunlight, therefore they live under debris or underground. Scarab Beetles (Family Scarabaeidae) The family Scarabaeidae is one of the largest beetle groups, with over 19,000 species worldwide and about 1,400 in North America. The larva feeds on dead wood below ground for five years before emerging as an adult. For these reasons the scarab was seen as a symbol of this heavenly life-cycle and of the idea of rebirth or regeneration for the Ancient Egyptians. It usually takes from 4 – 19 days for the eggs to hatch. Many Scarab beetle larva, larvae or Grubs (Scarabaeidae) of the Chafer beetle, Cockchafer or Rose beetles in the hand.
