Monkey beetle

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 to browse on the petals. The beetles are important pollinators of Aizoaceae and Asteraceae in grazed and ungrazed areas, as well as many others.

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.1 Many species visit flowers for pollen and nectar, or to browse on the petals. The beetles are important pollinators of Aizoaceae and Asteraceae in grazed and ungrazed areas, as well as many others.2

They tend to favor flowers of white, yellow, pink, orange, and blue pigments. They also tend to favor flowers of symmetrical, abstract patterns.34 Due to their pollination patterns, many plants evolved special features in order to attract monkey beetles, such as the Iridaceae which now have bright colors and symmetrical, unique patterns.

Genera

These 70 or so genera belong to the tribe Hopliini (subtribe: Hopliina):5

These 4 genera belong to the tribe Hopliini (subtribe: Pachycnemina):5
