Antweb is a site obessed with the world of Ants, so much so that they are attempting to take macro images of every know species of ant in the world - that's some 10,000+

"At this moment, more than one thousand trillion ants are scurrying all over the Earth. If every human climbed aboard one side of a scale, and every ant crawled onto the other side, the scale would just about balance.
Ants are everywhere. They are found under logs, in trees, in the stomachs of frogs, and underground. They use tools, herd and milk other animals, and live in highly organized colonies which can last for hundreds of years.
Ants are incredibly diverse. They can be as small as the point of a pin, or as big as a walnut. They can look as sleek as sports cars, or as bulky as tanks. AntWeb illustrates this diversity by providing information and high quality color images of many of the approximately 10,000 known species of ants."
