Started off taking butterworms and super worms. Once I got into the hard shit like mantids, there was no going back...lol
For real though. They're such cool feeders to raise. Next I'd like to try the Devils Flowers Mantis. But an oetheca is about $60

Worth it? I say yes! After fruit fly cultures, and habitats, it's easily a $100 investment. Maybe more. But I have to much fun doing it to care. And you can gutload them to the brim!
