In rainy climates, some breeds of termites attach special overhanging eaves to their nests. These eaves deflect downpours and keep the nests dry. The compass termite, an Australian breed, builds its nest in the shape of an axe head, the sides of which always point north and south. African termites in search of water will bore holes as deep as 130 feet into the Earth until they find the water table.

Ants keep slaves. Certain species, the so-called sanguinary ants in particular, raid the nests of other ant tribes, kill the queen, and kidnap many of the workers. The workers are brought back to the captors’ hive, where they are coerced into performing menial tasks.
