I'm pretty sure those are just the nymph stages of B. giganteus... Is this at Insectropolis in New Jersey? How was the visit, any info on what they keep there and if its worth visiting?

This is indeed Insectropolis in New Jersey. It's a small facility, with some cool rarer species, but overall it's a very, very small facility. I went through it in about 30 minutes.
