So long, monarch butterflies

It's been about a month since we first found our monarch caterpillars in the back yard, and a couple of weeks since we released the butterflies back into the wild. 


What an exciting experience it was to watch the caterpillars eat voraciously as they prepared to enter their pupa stage and then observe each day as we waited for them to emerge from their chrysalis.

As the first caterpillar's chrysalis began to turn transparent, and we could see the markings of the butterfly inside, we put a couple of zinnia blossoms from my mother's garden inside the terrarium.


After the butterfly emerged, late in the evening while we were out of the house, we gave it time to rest in the terrarium overnight.


The next day, we carefully transferred the butterfly to a portable carrier, being as gentle as possible so we wouldn't harm it or disturb the other caterpillar, still in its chrysalis in the terrarium.



Then we took the butterfly to my parents' house so that when it was released, it would be in the middle of a flower garden with lots of blooms, a perfect place to prepare for its long journey south.


The second butterfly emerged a couple of days later, apparently in the wee hours of the night. We went to bed and awoke the next morning to find it hanging from its chrysalis, gently turning back and forth.

We didn't disturb it for several hours, giving it plenty of time for its wings to dry before moving it to the carrier so we could release it in the garden. It flew up into a tree and sat there in the afternoon sun, fanning its wings.



We were able to tell by the markings that both of the monarch butterflies we raised were male. You can read more about determining the sex of a monarch butterfly here.



By now, I am sure our butterflies are well on their way to their southern destination. We hope that their journeys are safe and that their offspring return to our area for many years to come.

Very hungry caterpillars head toward the pupa stage

The two large monarch caterpillars we found earlier this week are doing well. We couldn't spot the tiny one today, but we hope it is just hiding and growing. I wanted to post an update on the larger two, though, because things are definitely moving along quickly.

It has been two days since we brought the caterpillars inside and put them in the terrarium. The bigger caterpillar has entered the J stage of development, attaching itself to a stem in preparation for forming its chrysalis.



The smaller caterpillar is still a virtual eating machine. Overnight, it had devoured most of its leaves, so we added fresh leaves from the plant in the back yard. If it has not entered its J stage tomorrow, we'll have to hunt in nearby fields for fresh milkweed, because almost all the leaves from the original vine are now gone.



In the meantime, you can see how much the hungry caterpillar munched out of this new leaf in just a minute or so after we replenished its supply.

Here's a link to another blog, the Texas Butterfly Ranch by Monika Maeckle, and her post all about raising monarch butterflies. She has some gorgeous photos and lots of helpful advice. I love that there are so many great resources where knowledgeable folks have shared their experience and families like ours can not only get a great homeschool science lesson, but also learn what we need to know to successfully help a few more monarch butterflies survive.

What kind of caterpillar is that?

Tonight, just before the sun went down, my younger daughter made a fantastic find in our back yard. She spotted a large caterpillar on a vine that was wrapped in and around the hibiscus that stands at the corner of the house. 


Thankfully, I hadn't been very good about weeding our flower beds this year, because if I had, that vine would have been removed early in the summer, and the monarch butterfly that laid her eggs its leaves would have had to search for someplace else to reproduce.

If you look closely at the leaf my daughters brought inside the house, you'll notice that not only was there a large monarch butterfly caterpillar, there was a tiny baby caterpillar as well!



The girls were so excited to discover that they'd found monarch caterpillars, we decided to see if we could gather some more leaves and let the caterpillars grow safely inside the terrarium we'd used earlier this summer to keep Jackie Chan, the ninja-like tree frog we'd raised from a tadpole. We had released Jackie Chan in a tree outdoors a few weeks after he completed his metamorphosis, so the terrarium was ready for a new inhabitant.

We found more of the same type of leaves, from a vine in the milkweed family, and on them we found another monarch caterpillar and a whole bunch more caterpillars we couldn't identify.

"What kind of caterpillar is that?" asked my daughters? "Will they hurt us?"



I didn't know, but the fuzzy creatures in striking black and orange, with funny white tufts sticking out here and there certainly looked alarming to me. "Don't touch," I answered. "Let's look them up."

Using the same research skills we practiced when we identified the strange fungus growing on our walnut tree this spring, we looked for information online that would help us identify the unknown caterpillar in the back yard.

We found a caterpillar identification tool that let us check distinguishing characteristics to help identify our species, and discovered in just a few clicks that the caterpillar sharing the vine with our monarchs was none other than the milkweed tussock moth, which is commonly found eating the same vegetation as monarchs.

We left these caterpillars alone, and took the other monarch inside, along with several fresh leaves, so they would have plenty to eat. Then we set about researching monarch butterflies, how to raise them, and how they live in the wild.

We can't wait to see our caterpillars change and grow into beautiful monarch butterflies, and release them to help maintain their population. And you can bet we won't be removing their vine of choice next summer. In fact, we might even give it a little trellis beside the hibiscus, so the butterflies will have a place to lay their eggs next year.
