Pillars of society

When we were leaving the park district after Tot Time today, we were hanging out side with Jill, and she and Charlotte were telling me about a caterpillar they saw. We looked around, didn't see it, and then suddenly it appeared. We were watching him, and then saw another. And another. And another until we had a count of FIVE caterpillars inching along in the grass and towards the park district garage. WEIRD.

I think they are American Dagger Moth caterpillars, from a quick search online. One of them excreted some strange bright green jelly-like substance - poo? chrysallis? - and then started to nibble on it. We felt somewhat disgusted, but didn't know if we should be or not.
