Help determining instar?

[ethanblaze1017]

Hi! I received a mantid as an extra in a package today that was unmarked. It wasn't labeled as male/female, unknown species (although I'm 99% sure it's p. Griffinni) and unknown age. My question is how Do I determine the in star? Are there characteristics to look for that would help? I'd be happy t post pictures if it would help anyone.

Thanks-

Ethan
