I saw this moth in my yard and googled it. Your site has EVERYTHING, so it was there… Is the polka dot wasp moth beneficial?? Thanks!
The adult Polka Dot Wasp Moth is a pollinator, so it is beneficial. If the caterpillar are too numerous, they might defoliate oleander and other plants. Leaves grow back on mature plants and the harm is temporary, and since we are not fond of oleander, we don’t consider the caterpillars to be a problem at all.
