These two bugs were nectaring on my buddleia. I'd never seen them before, so I grabbed the camera, got photos, and looked them up.

This Polka-dotted moth looks like a wasp, but it's a harmless moth, well... harmless unless it's larvae are eating your oleander.

This one also eats oleander, and it's polka-dotted as well, but its wings are a solid reddish color.

I've seen several Oleander moths since I took these (now old) photos, but they just won't sit still for another picture. I'll catch one eventually though.

At least one of their caterpillars is orange with black spines. It looked shaggy. It wasn't mine to keep, and I didn't have a camera on me.
