Giant ant

This ant in th tropical forest is as huge as my thumb. It form part of the life cycle of the forest and the wonderful nature. Yes. Need to protect the environment to ensure balanced ecosystem.
Sure I didnot use insecticide before taking this photograph. In fact I suffered with backache and right Sciatica after an hour chasing after this ant and attempted 20+ photos with this acceptable Digital photo. Of course on the 5th Nov 06, I climbed up the mountain( more than 15,000 inches high) to get this picture.
