Day six into our caterpillar watch and the cocoons have stayed the same color since day one.
They should look like this:
Aren't they beautiful? I love the gold rim and dots. If you look closely you can see the lines of the butterfly wings through the sides of the cocoon.
Caterpillars in this stage are much easier to keep track of. We had one caterpillar this week that was extremely ornery and kept escaping the bucket to hide who-knows-where. (At one point he managed to hide under the folds of the garbage bag.) After being dropped back into the vicinity he was so desperately trying to escape, he finally yielded and enveloped himself in the relative obscurity of a jade colored basket next to the rest of his friends. (We're still missing one though - don't really want to find out where its been hiding.)
