It's interesting to me that the queen has such stubby antennae. (the majors do too) It makes me wonder if ant communication is better when the antennae are of a similar scale.
Short antennae can also be an adaptation to make fighting less risky. But a queen like this would avoid fighting. (the majors are another story. They are called "marauder ants" because the minors ride on the majors backs, like a troop of Carthaginian soldiers on the back of an elephant. )
Hmmm.
