An exerpt from Speciesism by Joan Dunayer:,

"Many people have reported seeing ants construct a bridge over water or some other barrier - for example, by taking shreds of grass and, using their saliva, gluing them together. Ants of various species use bits of leaf, wood, dirt, or sand as food-collecting tools. Holding such material in their jaws, they dip it into food (e.g., honey, fruit pulp, or the body fluids of prey) until the food sticks or is absorbed. Then they carry the soaked material back to their colony. This strategy substantially increases the amount of food that they can carry. Why do humans consider it intelligence when chimpanzees use leaves as sponges to absorb water, or woodpeckers soak bark in honey that they then feed their young, but mere instinct when ants perform equally complex actions? Speciesism."

This quote was inspired by all the interesting insect programs recently at the Olympia Public Library. And, here is an article that illustrates the complexity of insect interactions.

A fascinating read. I highly recommend the book.
