we have a serious case of aphids in the garden, so yesterday we released hundreds of ladybugs to help us out. they pretty immediately went to having sex, but they do also consume two to three times their body weight each day, eating aphids and other bugs we don't want. this morning we already noticed a significant decrease in the number of bad bugs. yay. but we aren't sure where most of the ladys went...hopefully they are still in our yard.
