My yard is also registered as a monarch waystation. What that means is that I have enough varieties of flowers to feed them, and enough host plants for them to lay eggs on.
And finally, one of my caterpillar photos is being used on a sign for a permanent monarch exhibit at the John Ball Zoo in Grand Rapids, Michigan. They found it on flickr and asked if they could use it. Of course I said yes! The sign is already there, and the exhibit is open, but it hasn't been officially announced yet.

Here is the photo they are using:

04/23/2010: First milkweed of the season poking its head through the ground. Milkweed is the only thing that the monarch caterpillar can eat. The female seeks out milkweed to lay her eggs. The eggs then hatch and the caterpillars feed on it until they are ready to transform into a chrysalis. It takes 3-6 days for the egg to hatch, 7 to 10 days for the caterpillar to get to full size, and another 7-10 days for it to form into a full grown butterfly inside of the chrysalis.
05/14/2010: About 3 weeks later and the milkweed has gotten considerably larger. I can see the flower bud already.
August 17, 2010: The two photos below are being added to this blog because they are a very important part of the process and I wanted to include them. These are the best photos I've ever taken of a monarch laying an egg. As you can see, I got a picture of her the instant she touched the leaf and you can actually see the egg she just laid in the next shot. I was SO excited to get these two shots and see that they turned out! I'm still excited when I look at them LOL.
May 29, 2010: Saw a monarch this morning! It wasn't in my garden but of course the first thing I am going to do is to get out my magnifying glass and see if there are eggs. WooHoo! I found two eggs on my plants behind my house, but none in my actual butterfly garden. I'm sure there are more out there somewhere but I haven't had time to check. I wanted to get these in the house where they are safe and get a picture. When I bring them in the house I clip off the top part of the milkweed and I put them in a small bottle, and then in a small aquarium.
May 30, 2010: As you can see in the picture below, the egg has turned almost black. That is the caterpillar inside, ready to come out. I sat with my camera for about 2 hours and tried to get a picture of it coming out of the egg. Unfortunately it was getting late, I was beat from a long day, and I had to give up and get some rest. If I get another one at some point I will insert it after this picture.
May 31, 2010: Sometime in the middle of the night, a little caterpillar was born! I'm calling this one Doodle, as in Doodle Bug. He will be the subject for the blog this year. I have approximately 7 eggs at the moment. This is just the first batch, they will come back and lay eggs many times during the summer and I will harvest every time. As every year, we will start off with a grain of rice so you can see how tiny he is.
June 1, 2010: You can see by the photo below how much he has grown, just overnight! His stripes are more defined and his shape is much more streamlined. I now have 10 caterpillars!
June 3, 2010: He's still not bigger than the grain of rice but he's getting there. I 'think' he must have shed his skin not long before this picture was taken. They shed their skin 5 times during their life as a caterpillar. Each new stage is called an instar. You can see that he is now starting to get his antennae.
June 4, 2010: I think he's officially bigger than the grain of rice! His antennae have grown since yesterday and he's looking more and more like a full grown caterpillar.
June 6, 2010: Look how much he has grown in just two days! I love this stage! Their antennae look like puppy dog ears. They are much too big for his body LOL.
June 6, 2010: Another shot from the same day, just a different angle. He's really looking like a caterpillar should! I say he but truthfully you can't tell the gender until they form their chrysalis.
June 8, 2010: 8 days old now and it will probably only be two more days until he forms his chrysalis at the top of the aquarium. I have a screen top on there which makes it easy for them to spin their little web where they will hang for 7 to 10 days.
June 10, 2010: 10 days old now and he should head to the top at any moment. I've never had one go much beyond 10 days as a caterpillar. He's really beautiful, don't you think?
June 11, 2010: When I woke this morning to find Doodle in his J shape, I was SO excited! I've been raising butterflies for years now and this is the first time that one has hung itself on a piece of milkweed rather than the top of the cage. So hard to get nice pictures when you have a plastic lid or metal screen in the background.
June 11, 2010: Below is a series of photos that show the transformation from caterpillar to chrysalis. Lots of people think that the chrysalis forms around the caterpillar but actually the skin splits and the chrysalis is inside. I can always tell when they are ready to change because their little antennae get all twisted. It seemed like a long morning. I went out at around 8 a.m. to start watching for signs of the change. I was getting anxious because my son had a doctor's appointment at 9:30 and I didn't want to miss it. Doodle was very restless and there was a lot of movement but no twisted antennae.
We left at 9:15 and I was sure I was going to miss it. We came back home and I was happy to see he hadn't changed yet, and still no twisted antennae. We got home at around 10 and I sat until about 12:30 with nothing happening except a bit of twitching. I HAD to do some running so I reluctantly left and did what I needed to do. I came back in about a half an hour and when I looked, his antennae were twisted! I got my gear all set up. My gear is my tripod, camera, Doodle, a bucket full of cut milkweed for background green, and my phone in case it rings. It took about a half an hour more and then it began.
When he straightens out almost all the way I know it's time! All the way down by his head, the skin begins to split and you can see the green. It slowly splits while he is wiggling and trying to help it along. When the skin finally gets all the way to the top, he begins violently twisting and swinging to try and get the skin off. Once it falls to the ground he calms down. In about an hour or so the chrysalis has hardened and becomes more smooth looking.
June 11, 2010: This is Doodle's skin after he shook it off and it fell to the ground. You can still see his face, antenna and his legs.
