Since we are considering an addition to our house in the near future (square footage, people, not two little feet), we haven't ripped out the existing plants and gone full steam ahead with our plan to turn the garden outside our living room into a full blown butterfly smorgasbord. However, we definitely wanted to encourage the butterflies to come to our house, and come they have!
Two weeks ago I counted over 36 monarch caterpillars on our six little milkweed plants. I made an emergency food run during nap time one day to replinish the stash, because we didn't want to lose any caterpillars. I even had the guy at Palmer's take off the hitchiker caterpillars because we didn't want any more mouths to feed. They've all gone to chrysalis and since come out and flown away, but apparently they have decided to have babies. See?
So, yes, a trip to Palmer's is in our near future. Although we can't offer much for the butterflies as far as variety because we are constrained by space, they seem very happy to live in our garden. We have spent hours out there with the caterpillars, holding them and watching them eat, grow, turn to chrysalis and then butterfly. The boys have learned so much about butterflies this spring. It's been a great experience!
