I'm not sure what you have up there.
I found that guy right next to the tree where I found the same one 3 years in a row. I was hoping it was her again but way too small.
So after looking around, I'm pretty sure these tiny guys are first instar. It's frowned upon to ship before 2nd instar.
But... This will be a good experience. I hope they molt soon and everything should be good after that.
