The numerous Automeris species are very popular and in general fairly easy to rear, when you don't mind the urticating spines. The sting of some species can be rather unpleasant.
When it comes to correctly identifying the hundreds of species that belong to this American genus, that's more something for the experts. In recent years a handful of entomologists have created an enormous chaos in their enthusiasm of describing new species. They pretty much imagined a different Automeris behind every bush and tree, resulting in hundreds of species that are nearly impossible to distinguish from each other.
When you're just looking for some nice moths to rear, you can ignore all this and leave those discussion to the experts. In a couple of years, when the dust settles, we shall see how many of those 'new' species will be valid and how many will be synonymized.
