Proatta butteli. Forel, 1912. Specimen labels. The only species in its genus, Proatta butteli is found in southeast Asia and is strikingly similar in appearance to New World Attine species. Unlike the Attines, Proatta butteli is a predator and scavenger. Their prey includes isopods, centipedes and a variety of insects, including other ant species.Leaf-cutter ants in the genus Atta are also known for their morphologically diverse caste system , which reflects their complex division of labor , . For example, the overall body size of Atta cephalotes workers varies tremendously (i.e., head widths (HW) ranging from 0.6 mm to 4.5 mm [23] ), and these differences correspond to the tasks ...Nov 21, 2018 ... ... ant, (Atta mexicana) consumed in Mexico, is one of the common edible insects.

Efforts to evalu-ate microbial symbionts of leaf-cutting ants have focused so far mainly on Acromyrmex species, especially on the1. Introduction. Throughout the Neotropics, leaf-cutter ants of the genera Atta and Acromyrmex play a prominent ecological role in soil formation and have been studied at multiple spatiotemporal scales (Leal et al., 2014).Through their activities, leaf-cutter ants can modify the surrounding vegetation and directly influence the physical and chemical properties of the soil (Moutinho et al ...Hopper : You let one ant stand up to us, then they all might stand up! Those puny little ants outnumber us a hundred to one and if they ever figure that out there goes our way of life! It's not about food, it's about keeping those ants in line. That's why we're going back!Introduction. A key factor in the evolution of leafcutter ants (genus Atta and Acromyrmex) is the adaptation of task allocation system based on worker size variation fitted primarily to the utilisation of fresh vegetation as food resource to the symbiotic fungus that they cultivate (Wilson, 1980).In Atta sexdens, the distribution of activities related to foliar substrate treatment and fungus ...The species Atta sexdens, is a type of red ant with a broad, rounded head, slender thorax, and small, round abdomen.

It occurs from southernmost Mexico to Ecuador and Brazil, and from the Lesser Antilles as far north as Bardbados (Holldobler & Wilson, 1990). An apparently disjunct population occurs in the Atlantic Coastal Forests of Brazil (Solomon, 2007).Leaf cutter ants can be divided into two sub-species, atta and acromymex. Atta leaf cutter ants have a thorax or body that is comprised of three spines and a smooth exoskeleton on their upper thorax. Acromymex leaf cutter ants have a thorax with four spines and a rough exoskeleton.
