Research news on ants (order)

Ants are eusocial insects of the family Formicidae within the order Hymenoptera, which also includes bees and wasps. They are characterized by a distinct petiole forming a narrow waist between the mesosoma and gaster, elbowed antennae, and caste differentiation into reproductive queens and males and typically wingless sterile workers. Ants exhibit complex colony organization with division of labor, cooperative brood care, and sophisticated chemical communication via pheromones. Their ecological roles include soil modification, seed dispersal, predation, mutualisms (e.g., with aphids and plants), and scavenging, making them key model organisms in studies of social evolution, chemical ecology, and community dynamics.
