Remember the orange caterpillar? This is what it morphs to! Did some online research, and discovered that this is the Oleander Moth. They thrive only on the Oleander plant (which is supposed to be poisonous to other animals). The orange caterpillar is aptly called Oleander Caterpillar. The moth is also referred to as "Polka-dot Wasp Moth" because it resembles a wasp.
