Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1,500 species and 225 genera of rhinoceros beetles are known. [2]
Oryctes rhinoceros, also known as coconut rhinoceros beetle, Asiatic rhinoceros beetle, and coconut palm rhinoceros beetle, [2] is a large species of beetle (typically 4–5 cm long), belonging to the rhinoceros beetles subfamily Dynastinae. [1] Oryctes rhinoceros attacks coconut palms and other palms such as the economically important oil palm.
Most recent plant-eating beetles feed on flowering plants or angiosperms, whose success contributed to a doubling of plant-eating species during the Middle Jurassic. However, the increase of the number of beetle families during the Cretaceous does not correlate with the increase of the number of angiosperm species. [ 33 ]
Oryctes monoceros, commonly known as African rhinoceros beetle, is a species of rhinoceros beetles from the subfamily Dynastinae (family: Scarabaeidae) which is common in sub-Saharan Africa. [2] Its distribution extends from Senegal and Chad in the North to South Africa in the South and includes the islands of Madagascar, Seychelles and ...
Dynastes tityus is known by a number of common names, including eastern Hercules beetle, elephant beetle and ox beetle. [1] It was first given a scientific name by Carl Linnaeus, in his 1763 work Centuria Insectorum, where it was called Scarabaeus tityus; when Linnaeus' genus Scarabaeus was divided into smaller genera, S. tityus was renamed Dynastes tityus.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The metallic green and brown insects are known to feed on more than 300 species of plants, including roses, ornamental trees and vegetables. ... Japanese beetles were first introduced to the ...
One of the largest beetles found in Europe, Oryctes nasicornis reach a length of 20–42 millimetres (3 ⁄ 4 – 1 + 3 ⁄ 4 inches), with a maximum of 47 mm (1 + 7 ⁄ 8 in). [1] The elytra are reddish brown with a glazed appearance, while the head and pronotum are slightly darker. The underside of the body and the legs are covered with long ...
