We have been learning the importance of camouflage to a caterpillar if they do not want to be eaten by a bird.  Some caterpillars are really easy to find but others look like the plants they live on.  We found that red and blue caterpillars were very easy to find but the green and brown ones were very hard.   In fact I think that we lost lots of brown and green caterpillars, we hope that Chestnut can find them all tomorrow.
