The mantis with an unusual pattern on its back is Pseudocreobotra wahlbergii, I raise them myself. Attached is a L4 nymph of the same species in its threat pose. Feel free to crop the image.
Thank you so much Ian,
You have single-handedly identified all of our unidentified exotic Mantids. Next time we get one that stumps us, we plant to contact you. Thanks again.
