> The haplodiploidy hypothesis, though nice, is not without its problems. Firstly, there are plenty of species with haplodiploid genetics which do not form eusocial colonies. That is not a problem. Reproductive fitness must always be measured relative to an environment. Just because colony life is a successful strategy for haplodiploid species in some environments does not mean it will be a successful strategy in all environments. You can see this in other species. Female lions live mostly in cooperative groups while male lions and all other large cats (leopards, cheetahs, and tigers) are solitary.
