Ants and bees belong to the Hymenoptera, which is the third largest group of insects. Many members of this group are social insects. Some of the behaviors exhibited by this group are among the most amazing in the animal world.
I have photographs of ants "farming" treehoppers, and of an amazing relationship that ants have to a local flower.Ants are amazing creatures. Ants tend mushroom crops, enslave other ant species, "farm" a wide variety of insect species, and store honey in the bodies of certain worker ants. These behaviors hardly touch the surface.
Social bees and wasps also lead interesting lives, with many different lifestyles.
Some of the solitary wasps lead the most interesting lives of all, laying eggs on living insects which continue to live until the wasp larva consume all of their bodies, and then pupate themselves.
I can't begin to touch the diversity involved in this group. I can only hope to show a few things that caught my eye.
