Scarabaeinae
The scarab beetle subfamily Scarabaeinae consists of species collectively called true dung beetles (there are also dung beetles in other subfamilies and families). Most of the beetles of this subfamily feed exclusively on dung. However, some may feed on decomposing matter including carrion, decaying fruits and fungi. Dung beetles can be placed into three structural guilds based on their method of dung processing namely rollers (telecoprids), dwellers (endocoprids) and tunnelers (paracoprids). Dung removal and burial by dung beetles result in ecological benefits such as soil aeration and fertilization; improved nutrient cycling and uptake by plants, increase in pasture quality, biological control of pest flies and intestinal parasites and secondary seed dispersal. Well-known members include the genera '' Scarabaeus'' and '' Sisyphus'', and '' Phanaeus vindex''. Description Adult dung beetles have modified mouth parts which are adapted to feeding on dung. The clypeus is expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dung Beetle
Dung beetles are beetles that feed on feces. All species of dung beetle belong to the superfamily Scarabaeoidea, most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae (scarab beetles). As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed ''true dung beetles''. There are dung-feeding beetles which belong to other families, such as the Geotrupidae (the ''earth-boring dung beetle''). The Scarabaeinae alone comprises more than 5,000 species. As they do not belong to a single group sharing a common ancestor, there is a diversity in the behavior of dung beetles, including the iconic dung-rolling behavior revered by Ancient Egyptians as Khepri rolling the sun across the sky. Taxonomy Dung beetles are not a single taxonomic group (they are not monophyletic); dung feeding is found in a number of families of beetles, so the behaviour cannot be assumed to have evolved only once. Below is the taxonomy of beetles, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phanaeini
Phanaeini is a tribe of dung beetles in the family Scarabaeidae. There are about 12 genera and 200 described species in Phanaeini. They are native to the Americas with the highest species richness in the Neotropics. They are mostly coprophagous Coprophagia ( ) or coprophagy ( ) is the consumption of feces. The word is derived from the Ancient Greek "feces" and "to eat". Coprophagy refers to many kinds of feces-eating, including eating feces of other species (heterospecifics), of o ... or necrophagous, but some of the least known genera appear to be myrmecophilous (likely in ''Dendropaemon'' and ''Tetramereia'', possibly also in ''Homalotarsus'' and ''Megatharsis''). They are medium-sized to large beetles (''Coprophanaeus'' includes some of the largest dung beetles), often with bright metallic colors, and often with horns on their heads (especially in the males, less frequently in the females). Genera These 12 genera belong to the tribe Phanaeini: * '' Bolbites'' Haro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ateuchini
Ateuchini is a tribe of dung beetles in the family 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 tre .... There are at least 30 genera and 370 described species in Ateuchini. Genera These 30 genera belong to the tribe Ateuchini: * '' Aphengium'' Harold, 1868 * '' Ateuchus'' Weber, 1801 * '' Bdelyropsis'' Pereira, Vulcano & MartÃnez, 1960 * '' Bdelyrus'' Harold, 1869 * '' Besourenga'' Vaz-de-Mello, 2008 * '' Bradypodidium'' Vaz-de-Mello, 2008 * '' Degallieridium'' Vaz-de-Mello, 2008 * '' Deltorhinum'' Harold, 1867 * '' Demarziella'' Balthasar, 1961 * '' Eutrichillum'' MartÃnez, 1969 * '' Feeridium'' Vaz de Mello, 2008 * '' Genieridium'' Vaz-de-Mello, 2008 * '' Leotrichillum'' Vaz-de-Mello, 2008 * '' Martinezidium'' Vaz-de-Mello, 2008 * '' Nunoidium'' Vaz-de-Mello, 2008 ...
