Advertisement After five weeks of protecting these egg cases from certain disaster, I was incredibly to see that my egg cases have finally sprung for spring! Before these hatched, I was raising three live mantises. A lot of people stay away from mantises due to their short life spans, but they are among my favorite animals to take care of. Easy to handle, interesting to watch, and very entertaining to feed. A lot of people I've shown these two hate insects and arachnids, but they think these guys are pretty darn cute... I've been breeding them for natural pest control, they have protected my succulent plants from certain doom. Once infested with aphids, I've watched them make a meal out of nearly all of them.
