Countless is a lot, lol. Oh you only had three different types, though? Interesting. I'm sure you know about those particular genera, then.
I'm pretty much just a pro at Stagmomantis Limbata, right now, lol. I can't wait to get my own ghost mantids, those are very interesting in appearance. Wow, since 5? That's freakin' long, lol! I only started this year. I've never seen one in the wild, before, myself. So I buy mine online. 500 is an awesome amount! That's sad that your Tenodera Sinensis got eaten by ants. Ants these days, huh? Lol. And good idea about the hanging so they're safe from the ants.
You currently own 12? Dang! How are you able to take care of them all? Lol.
