The genome sequence of the leaf-cutter ant Atta cephalotes reveals insights into its obligate symbiotic lifestyle. [PDF]
PLoS Genetics, 2011 Leaf-cutter ants are one of the most important herbivorous insects in the Neotropics, harvesting vast quantities of fresh leaf material. The ants use leaves to cultivate a fungus that serves as the colony's primary food source.

Dietary diversity, sociality, and the evolution of ant gustation
Frontiers in Ecology and Evolution, 2023 Ants have remarkably diverse diets and extraordinary species richness, making them an excellent model system to study the evolution of taste. In this entirely eusocial clade, food choice and the mechanisms that regulate feeding have both individual and ...

Occurrence of Atta cephalotes (L.) (Hymenoptera: Formicidae) in Alagoas, Northeastern Brazil [PDF]
Neotropical Entomology, 2005 Atta cephalotes (L.) presents a wide distribution in the Neotropical region. In Brazil, this species is disjunctly distributed in the Amazon region and in the states of Maranhao, Pernambuco and southern Bahia, all of which belong to Northeast Region. Here we report on a survey of Atta colonies in 42 remnants of the Atlantic rainforest in Alagoas and ...

A biomechanical model for the relation between bite force and mandibular opening angle in arthropods
Royal Society Open Science, 2023 Bite forces play a key role in animal ecology: they affect mating behaviour, fighting success, and the ability to feed. Although feeding habits of arthropods have a significant ecological and economical impact, we lack fundamental knowledge on how the ...

Herbivory of Atta Cephalotes (Hymenoptera: Myrmicinae) on Three Plant Substrates
Revista Colombiana de Entomología, 2008 A recent study suggests a significant reduction of herbivory by the leaf cutting ant, Atta cephalotes , in plantations of the pioneer tree ( Montanoa quadrangularis (Asteraceae)) when associated and fertilized with green foliage of the Mexican sunflower

Molecular Ecology, Volume 35, Issue 11, June 2026.ABSTRACT Division of labour in reproduction and in task performance are two hallmarks of insect societies. Bumble bees and honey bees are both classified as eusocial, but differ in the social organization of their colonies and in the hormonal regulation of division of labour.

Revista Colombiana de Entomología, 2016 The external portion of Atta cephalotes nests is composed of three areas: openings, trails, and cutting; where cutting and transporting leaves, sharing information, and defending the nest take place. The richness of the fauna of these areas is not only dependent on the interactions among ants,

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Ecology and Evolution, Volume 15, Issue 12, December 2025.Camponotus lateralis (C, D) mimics regional color morphs of Crematogaster (A, B). Field trips brought insights into ecology, trail sharing, sexual reproduction, colony foundation, nest defense, and predation pressure of this mimetic ant. We found that the mimicry is Batesian and suggest several preadaptations for its evolution.
