The reddish ants, called Weaver ants, usually live in the tropical forests of Africa and India. But the one in the photo seen here is from the front yard of our house in India. They build elaborate nests using the leaves of the tree they live in. The ants have a strong chemical in their bodies called formic acid. The ants use the formic acid to protect their nests. They are not as harsh as the smaller red ants who are less forgiving than their bigger counterparts.
