Isn't inability to reproduce sterile?
Yes, which is roughly synonymous with 'infertile'.
Unfertilized, on the other hand, means that whether or not she can produce offspring, she has not mated. This would most easily be characterized by her producing offspring which develop into males.
Claims of infertility are rampant on the forums, but I've never actually seen anybody investigate their queen's failure to raise workers. The word shouldn't be used interchangeably with "I don't have any idea why my queen failed".

If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.
Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.
