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]
Some species feed on the larvae of moths and other beetles, as well as mites. Since much of their prey are agricultural pests, coccinellids are considered to be beneficial insects . [ 47 ] [ 48 ] [ 49 ] A 2009 metastudy by Hodek and Honěk found that aphid-eaters constituted around 68 percent of species that live in temperate areas but only 20 ...
Male Hercules beetles may reach up to 173 mm (7 in) in length (including the horn), making them the longest species of beetle in the world, if jaws and/or horns are included in the measurement. [3] [6] The size of the horn is naturally variable, more so than any variation of the size of legs, wings, or overall body size in the species. This ...
The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; [2] new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species.
This article classifies the subgroups of the order Coleoptera down to the level of families, following the system in "Family-group names in Coleoptera (Insecta)", Bouchard, et al. (2011), [1] with corrections and additions from 2020, [2] with common names from bugguide.net.
The females and larvae have a flattened, dark body with large scales over the head, resembling trilobites, hence the informal names trilobite beetle, trilobite larva or Sumatran trilobite larva. In contrast, the males are much smaller, 8–9 mm, resembling other lycid beetles. Species are found in tropical forests of India and South-east Asia.
Larvae of the black carpet beetle Attagenus megatoma may grow up to 1 ⁄ 2 inch (13 mm) and be yellow to brown in color. Other types of carpet beetle are regularly 1 ⁄ 4 to 1 inch (6.4 to 25.4 millimetres) long and covered with dark setae. Certain species have distinctive tufts of setae extending from their posterior end.
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. [1]
