I found 3 on a nettle plant and took them home to raise. Two pupated a couple days later and eclosed in approx. 10 days, and I released them. One of them never pupated, but instead, some tiny wasps hatched out of the poor thing while it was still alive. I know that's what happens out there in the big wide world, but...ick! I flushed them so my other bugs wouldn't get parasitised
