Ant larvae are fascinating. I wish more studies of ant behavior included them.

While not as flashy as adults, immature ants are just as important to the functioning of a colony. Not just for the obvious reason that all ants must grow up from larvae, either. It’s that larvae are the gut of the colony.

Larvae are the only individuals that can eat solid food. Adults can’t pass solids through their extremely narrow guts. Yet protein-rich foods, like arthropod carcasses, are typically meaty. So if an ant colony is to use these resources, the larvae must digest them first. In most species, the grubs can then regurgitate a liquid protein slurry back to the adults.

Anyway, this post is really just a long-winded excuse to share the above photograph of charmingly furry Gnamptogenys larvae making quick work of some fire ants their older sisters have brought them.
