Thanks for posting. Very interesting article.
This ant species Ooceraea biroi is fascinating. Hymenoptera (ants, bees and wasps) generally reproduce genetically via haplodiploidy, where females have double set of chromosomes and males only a single set and there is usually only one egg-laying individual per colony (most hymenopterans are eusocial) - the queen. These little critturs, though eusocial, have no queen and no males.
