Leafcutter Ants
Leafcutter ants are fungus-growing ants that share the behaviour of cutting leaves which they carry back to their nests to farm fungus. Next to humans, leafcutter ants form some of the largest and most complex animal societies on Earth. In a few years, the central mound of their underground nests can grow to more than across, with smaller radiating mounds extending out to a radius of , taking up and converted into 3.55 m individuals. Leafcutting groups Leafcutter ants are any of at least 55 species of leaf-chewing ants belonging to the three genera '' Atta'', '' Acromyrmex'', and '' Amoimyrmex'', within the tribe Attini. These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico, and parts of the southern United States.. Leafcutter ants can carry up to 50 times their body weight and cut and process fresh vegetation (leaves, flowers, and grasses) to serve as the nutritional substrate for their fungal cultivates. The leaf cutter an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Amoimyrmex striatus'' is a species of leafcutter ant found in the Neotropics.Cristiano, M., Cardoso, D., & Fernandes-Salomão, T. (2013).

Acromyrmex
''Acromyrmex'' is a genus of New World ants of the subfamily Myrmicinae. This genus is found in South America and parts of Central America, México and the Caribbean Islands, and contains 33 known species. Commonly known as " leafcutter ants" they comprise one of the two genera of advanced attines within the tribe Attini, along with '' Atta''. Anatomy ''Acromyrmex'' species' hard outer covering, the exoskeleton or cuticle, functions as armour, protection against dangerous solar waves, an attachment base for internal muscles, and to prevent water loss. It is divided into three main parts; the head, thorax, and abdomen. A small segment between the thorax and abdomen, the petiole, is split into two nodes in ''Acromyrmex'' species. The antennae are the most important sense organs ''Acromyrmex'' species possess, and are jointed so the ant can extend them forward to investigate an object. It can retract them back over its head when in a dangerous situation, for example, a fight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen individuals often living in small natural cavities to highly organised colonies that may occupy large territories with sizeable nest that consist of millions of individuals or into the hundreds of millions in super colonies. Typical colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gy ...
