Smaller Parasa Moth

This tiny green and brown moth was hanging onto the exterior wall of a park building. There is another very similar Parasa moth species in our area, but I think this is the smaller of the two. P. chloris has a strange-looking slug caterpillar with stinging spines that looks like something out a bad sci-fi movie. Meanwhile, its relative Parasa indetermina (Stinging Rose Caterpillar) has a slug caterpillar that is also stinging, but that is brilliantly colored and looks like something out of an art glass exhibit. I would love to see either of unusual larva.
