I met this inchworm this weekend. He seemed friendly enough, inching along the picnic table, until we nudged him. Quick as anything he reared up, back legs anchored firmly and front legs splayed, looking for all the world like he would gladly chew our faces off with his angry little jaws.
I took notes. I'm not sure that this is a bad way to react to all of this in the unfortunately lately and now-and-again.
