Bees, Wolf Howls, Whale Song, have all been mapped to codified structure. They are languages. Dolphin Chirp and Finch Song is being mapped successfully as well.
The Figure 8 Waggle Dance of the Bee encodes for distance, direction, wind drift, quality of pollen, and even suggests an optimal route to the booty.

Ants, on the other hand, seem not to have a language. Rather than communicating with any syntactically structured language, their movements are more like plants, being a system of triggers and switches, set off by pheromones on the trail. That’s not language, and it is not communication. That’s simple cause/reaction to stimuli. There is no meaning conveyed and no codified structure.
What’s interesting about ants though, is that as individuals, they act as non-intelligent creatures. But as an entire colony, a quasi-intelligence seems to appear.
