I used to keep terrestrial creepy crawlies, and some other native things from my area like pond skaters and aquatic beetles. I had a couple of tarantulas too and at one point I had a small mealworm farm that wasn't to feed anything, just to have the beetles. I guess they're from the same family or thereabouts as what you're getting? Unfortunately I had to stop with those sorts of things when academic stuff started to get hairy and dropped back to just doing aquariums. I wouldn't mind setting up another mealworm farm at some point though since it's so easy to maintain.
