5-699: Monkey beetles are scarab beetles , a group of around 70 genera and 850 described species within the tribe Hopliini . The placement of this tribe within the family Scarabaeidae is uncertain between Melolonthinae and Rutelinae . Many species visit flowers for pollen and nectar , or browse on the petals. The beetles are important pollinators of Aizoaceae and Asteraceae in grazed and ungrazed areas, as well as many others. They tend to favor flowers of white, yellow, pink, orange, and blue pigments. They also tend to favor flowers of symmetrical, abstract patterns Due to their pollination patterns, many plants evolved special features that attracted monkey beetles, such as
10-460: 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. The largest fossil scarabaeid was Oryctoantiquus borealis with a length of 50 millimetres (2.0 in). The C-shaped larvae , called grubs, are pale yellow or white. Most adult beetles are nocturnal, although
15-1166: The Iridaceae which now have bright colors and symmetrical, unique patterns. These 70 genera belong to the tribe Hopliini: This Scarabaeidae -related article is a stub .

Scarabaeidae The family Scarabaeidae , as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles . The classification of this family has undergone significant change. Several groups formerly treated as subfamilies have been elevated to family rank (e.g., Bolboceratidae , Geotrupidae , Glaresidae , Glaphyridae , Hybosoridae , Ochodaeidae , and Pleocomidae ), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023). Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between 1.5 and 160 millimetres (0.059 and 6.3 in). They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into
20-472: The Scarabaeidae are Japanese beetles, dung beetles , June beetles , rose chafers ( Australian , European , and North American ), rhinoceros beetles , Hercules beetles and Goliath beetles . Several members of this family have structurally coloured shells which act as left-handed circular polarisers; this was the first-discovered example of circular polarization in nature . In Ancient Egypt ,
25-466: The flower chafers ( Cetoniinae ) and many leaf chafers ( Rutelinae ) are active during the day. The grubs mostly live underground or under debris, so are not exposed to sunlight. Many scarabs are scavengers that recycle dung, carrion , or decaying plant material. Others, such as the Japanese beetle , are plant-eaters , wreaking havoc on various crops and vegetation. Some of the well-known beetles from
