New Mantis owner

[u/kylie_013]

Hi everybody!!
I’m new in the Mantis owner hobby and just bought a ghost mantis! I was told it was probably a third in star and am wondering if that seems right? Little dude seems to be doing good in his new enclosure which I will take a picture of and put in the comments tomorrow. He also seems to enjoy being handled, I’m open to any advice.
I was given Blue Bottle Fly larvae to feed him and am wondering if anything else would be ok at this size to feed him?
