Seems like your having fun ! Ant lions are fun little insects. I had one for awhile in a jar the size of a film canister, feeding it ants now and again it did very well.. I've never had solitary wasps but I've kept a colony of paper wasps, while they scare me in the fact I don't want to get stung (I never have been stung) they are pretty interesting little creatures to watch. Good luck!
