Green Caterpillar

I captured this creature today in the farm after going there to observe the herbicides I sprayed on grasses. This creature is called caterpillar.

The grasses have started dying and losing strength as you could see. They have turned deep greenish they were before to yellowish.

I feel the creature is trying to run away and get a better place cause the farm has already been contaminated with herbicides. The camouflage of its body is in harmony with the grasses. It will hardly be noticed by predators.
