The Central and South American Paradirphia genus suffered a lot the past decade from overactive entomologists. The number of species described more then doubled in less ten 10 years. For most people it has become impossible to see the differences between all these new species. The next decade will probably be used by other entomologists to lower the number significantly.
The rearing is usually quite easy. All members have urticating caterpillars, so handle with caution.
