Such fine-tuning of reproduction may help groups of close relatives avoid reproductive competition and coordinate their efforts to increase their joint success. The new findings shed light on the ...

Male yellow crazy ants (Anoplolepis gracilipes) are chimeras of two separate genetic lineages, researchers report in a study that reveals a unique mode of reproduction in this species – one previously ...

In the clonal raider ant (Ooceraea biroi), workers in a colony alternate between caring for larvae and laying eggs in a coordinated cycle. Researchers at the Max Planck Institute for Chemical Ecology ...

Queen ants, the only individuals in a colony that can lay eggs, can also live for decades—up to 10 times longer than workers. But for years, scientists didn’t understand why. A new study published ...

In social species, the presence of several reproductive individuals can generate conflict. In social insects, as queen number increases, individual oviposition rate may decrease because of direct and ...
