To meet their need for nitrogen in the restricted foraging environment provided by their host plants, some arboreal ants deploy group ambush tactics in order to capture flying and jumping prey that might otherwise escape. Here we show that the ant Allomerus decemarticulatus uses hair from the host plant's stem, which it cuts and binds together with a purpose-grown fungal mycelium, to build a spongy ‘galleried’ platform for trapping much larger insects. Ants beneath the platform reach through… 

Arboreal Ants Use the “Velcro® Principle” to Capture Very Large Prey

This study investigated the predatory behavior of the ant Azteca andreae which is associated with the myrmecophyte Cecropia obtusa, and found that up to 8350 ant workers per tree hide side-by-side beneath the leaf margins of their host plant with their mandibles open, waiting for insects to alight.

Prey Capture Behavior in an Arboreal African Ponerine Ant

The predatory behavior of Platythyrea conradti, an arboreal ponerine ant, whereas most species in this subfamily are ground-dwelling is studied, where the workers are able to capture a wide range of prey, including termites and agile, nocturnal insects as well as diurnal insects that are inactive at that moment of the Nyctemeron.

Rainforest Canopy Ants: The Implications of Territoriality and Predatory Behavior

The methods that permit us to study “arboreal ant mosaics” are discussed, which are good predators that use group ambushing to catch flying insects on their host tree foliage and are frequently used as biological control agents.

A dolichoderine ant that constructs traps to ambush prey collectively: convergent evolution with a myrmicine genus.

This study shows that the genus Azteca presents the largest panel of group hunting strategies by ants and that there is polyethism related to polymorphism, as hunting workers are larger than their nestmates.

The Dynamics of Foraging Trails in the Tropical Arboreal Ant Cephalotes goniodontus

The foraging behavior of the arboreal turtle ant, Cephalotes goniodontus, was studied in the tropical dry forest of western Mexico, suggesting that the allocation of foragers to different trails is regulated by interactions at the nest.

Altruism during predation in an assassin bug

Zelus annulosus is an assassin bug species mostly noted on Hirtella physophora, a myrmecophyte specifically associated with the ant Allomerus decemarticulatus known to build traps on host tree twigs

Predation and aggressiveness in host plant protection: a generalization using ants from the genus Azteca

It is deduced that the workers’ predatory behaviour and territorial aggressiveness combine in the biotic defence of their host tree.

Foraging and Predatory Activities of Ants

In this chapter, the foraging habit and the predation biology of these foragers are explored, in which the sequence of attack, their interactions, and invasion caused are discussed.

Protection in an ant–plant mutualism: an adaptation or a sensory trap?

Ant-plant mutualism: a dietary by-product of a tropical ant's macronutrient requirements.

The defensive behavior of some phytoecious ants is a by-product of their need for external protein sources; thus, the consumption of insect herbivores by ants benefits both the ant colony and the host plant.



Coordinated group ambush: A new predatory behavior inAzteca ants (Dolichoderinae)

A new technique used by ants (Azteca cf. lanuginosa) in the Brazilian Cerrado to capture large mobile insects, most of them being two times longer than the ants.

The role of resource imbalances in the evolutionary ecology of tropical arboreal ants

Dietary ratios of CHO:protein play an important and previously unrecognized role in the ecology and evolution of ants generally and modifications of worker digestive systems in certain ant sub-families and genera represent key innovations for handling and processing large volumes of liquid food.

Balancing between mutualism and exploitation: the symbiotic interaction between Lasius ants and aphids

Ants not only attended their aphid partners, but also preyed on them, and the average predation rate increased eightfold when ants were offered the alternative of sugar, whereas alternative prey had no significant effect.

Tetraponera ants have gut symbionts related to nitrogen–fixing root–nodule bacteria

It is argued that pouch bacteria have been repeatedly ‘domesticated’ by the ants as nitrogen–recycling endosymbionts, the first finding of symbionts related to root–nodule bacteria in animals.

Protective ant-plant interactions as model systems in ecological and evolutionary research.

Protective ant-plant interactions, important in both temperate and tropical communities, are increasingly used to study a wide range of phenomena of general interest and offer rich material for studying ant social evolution in novel contexts.
