Driver ants form nomadic colonies that can exceed a million workers and hunt almost continuously because they cannot store food; raiding parties are led by soldiers with oversized heads and scissor-like mandibles that dismantle prey from insects to small vertebrates, and their aggressive foraging can even threaten humans.
A Chinese national, Zhang Kequn, was arrested at Nairobi's Jomo Kenyatta International Airport for attempting to smuggle about 2,248 live queen garden ants (1,948 in test tubes and 300 hidden in tissue rolls) to China, signaling ties to a broader ant‑trafficking network. The ants, protected under biodiversity treaties, are regulated trade; prosecutors asked to forensically examine his devices as investigations widen and more arrests are anticipated. A similar high‑profile case last year underscored the seriousness of wildlife trafficking in Kenya.
Six Cretaceous amber specimens show ants living close to mites, wasps, and spiders, suggesting ancient ecological interactions and possible mutualistic or parasitic relationships, with future micro-CT analysis to clarify how these organisms interacted.
A Max-Planck study shows urban ozone degrades alkene-based ant odors, blurring nestmate recognition and impairing brood care across six species, revealing a surprising way air pollution can disrupt eusocial colonies.
Lycaenidae caterpillars have evolved to manipulate ants through rhythmic acoustic and chemical signals, enabling ants to raise them in their colonies until they metamorphose into butterflies, a striking example of interspecies deception and mutualism.
Researchers describe a three-way symbiosis in the Amazon between the shrub Hirtella physophora, the ant Allomerus decemarticulatus, and a cultivated fungus. The ants fashion a trap by cutting plant hairs and using fungal adhesive to build a stem platform with pores, where they ambush prey much larger than themselves; crickets are overcome and consumed. The plant gains defense and sugar rewards; the ants get prey, and the fungus feeds on waste, making a rare win-win-win interaction.
A new study reveals that sick young ants release a smell signaling worker ants to destroy them to protect the colony, a self-sacrificial act not performed by queen ants due to their stronger immune systems. This behavior highlights the colony's collective effort to prevent disease spread, with sick worker ants leaving the nest and infected pupae being sacrificed through chemical signals, ensuring the survival of the colony's genes.
Scientists discovered that sick ant pupae release a smell that signals worker ants to destroy them, a self-sacrificial act to protect the colony from infection, with queens not participating due to their stronger immune systems. This behavior highlights altruism in social insects and parallels disease management strategies in other species.
A study shows that black garden ants modify their nest structures to reduce disease spread, inspiring potential human architectural strategies for epidemic control.
Scientists in Denmark used red wood ants to ferment milk into yogurt, creating unique dishes served at a Michelin-starred restaurant, highlighting the potential of insects in food innovation while emphasizing safety concerns and ecological considerations.
Some ants, like M. ibericus, exhibit extraordinary reproductive behaviors, including laying eggs that hatch into another species, through mechanisms like removing their own genetic material from eggs and cloning males, challenging traditional understanding of species and evolution.
Researchers discovered that Mediterranean harvester ants (Messor ibericus) can produce male offspring of a different species (Messor structor), using these males to create hybrid workers and support their colony, revealing a unique exception to the typical rule that offspring belong to the same species as their parents.
The article discusses the bizarre reproductive strategy of Iberian harvester ant queens, who clone male builder ants from another species to create a dependent hybrid workforce, a practice called 'xenoparity,' highlighting a unique and complex form of interspecies dependency and evolution in ants.
Iberian harvester ants (Messor ibericus) can clone males of a different species, Messor structor, to produce hybrid workers and maintain their colony, even in areas where M. structor is absent, showcasing a remarkable and almost unimaginable biological system.
A study highlights the significant evolutionary influence of social insects like ants and termites over the past 50 million years, especially on mammals that have adapted to feed on them, though such specialized diets may pose risks if insect populations decline. The research underscores the powerful role of social insects in shaping biodiversity and environmental change, with ongoing exploration into their impact using natural history as an archive.
