 Polymorphic male ants? 

Te section Polymorphism#Ants surprises me by claiming that polymorphism is more common among male ants than among the females. It also claims that there are non-reproductive male ants. Recalling that all I've read about ants was to the effect that the (haploid!) males sole task in the colonies is reproductive, i find this rather confusing. Could ""male"" possibly be a misprint for ""female""? If there is any polymorphism in male ants (apart from them taking part in the sexual dimorphism), I'd like to see a reference, or a wp link.
