The stunning Polka Dot Wasp Moth is the adult stage of the Oleander Caterpillar, here pollinating our Backyard Loquat Trees. It is rare to see and get film of these elusive beauties which flutter around slowly in the daytime (Syntomeida epilais Walker). Its dangerous wasp-like appearance and unusual color patterns say to potential predators like birds – stay away – thus they are perfectly safe to feed on pollen in the daytime alongside the bees and other pollinators. Their caterpillars are only destructive to Oleander Trees which are highly poisonous.
