Sorry this is probably not a good place to raise this question, but I have never seen a S. Carolina get beyond 4 inches, could you show us a pic? 6 inches (15 cm) would make it one of the largest mantis in Northern America. Here is a pic of a large (well long is a better word) Iscnomantis gigas taken from my friend Lars, and i thought that was a giant!! Stagmomantis being bulkier will be a monster if it is a 6-incher!
