I found these 2 already hatched caterpillars. I'm betting the big one will probably go into chrysalis stage sometime this weekend.
I also found 12 caterpillar eggs! I like raising the caterpillars from eggs. It takes a little big longer, but I have much more success with raising them to butterflies because there's no chance of any of the caterpillars being parasitized by wasps or flies when they grow up inside my house. If you're wondering exactly what I'm doing with these eggs, it's a moistened washcloth in a pie plate. I just cut off a small portion of the leaf where the egg is laid. The washcloth will keep the leaf moist and also from curling up. Plus, it's much easier to monitor how close the eggs are to hatching when they're visible like this. Once the tiny caterpillar hatches, I just put it (and the little leaf fragment) on a fresh milkweed leaf and the caterpillar will be ready to start eating and growing.
This last picture has nothing to do with the monarch ranch, but when I was editing the photos I found this one on the card in my camera that I had taken a few weeks ago. It's Mrs. Bluebird peeking out of the door of her house. Isn't she cute? Four bluebird babies were successfully fledged from this house.
