Found in the tropics of Central America. Need help to identify.

That is the oleander moth, also known as the polka-dot wasp moth - beautiful as an adult and larva. Nice picture. The adult female emits an ultrasonic signal to attract males rather than using chemical pheromones that most other moths use. Oleander Caterpillar - Syntomeida epilais Walker

Thanks! Here in Central America, sometimes we think we are the only people who sees these things! A moth! Who'd a thunk it!!
