When you've seen one, you've seen them all. That is almost true in the case of the Rothschildia genus. Two types of caterpillars (and their moths) dominate: the lebeau/cincta type and the orizaba type. Many species in these two groups look almost identical (moths and caterpillars). Unfortunately, it's mostly species out of these groups that are commonly available. Of course, among the now more then 45 Rothschildia, there are species that are different, very different even, but they are rarely seen in captivity. The members of this American genus are, in general, fairly easy to rear.
