A queen Amblyopone ant in the brood nest with eggs (lower right) and larvae.  This species has multiple queens in a single nest, and it is possible that this ant's missing hind leg was removed in a dominance fight with another queen.  Queens and workers are similar in appearance in Amblyopone, but queens have larger eyes and a bulkier mid-section.
