Waiting for the Monarch

I have not forgotten about our chrysalis. Although a monarch chrysalis, in nice warm weather, normally gestates about two weeks, my life went into spin cycle right after the last chrysalis post, with multiple speaking engagements at far-flung places.

So picture Wayne making a bead curtain with his fingers, and time-travel with me back to the caterpillar Liam named Combo (one of my pet names for him, as it happens). Combo went into J formation, split his skin down the back, and became a sea-green chrysalis, which then hung for two weeks. We almost forgot about it, but then one day Combo's chrysalis went slightly transparent, and within a few hours it went completely dark.
The chrysalis covering goes from opaque to transparent, and the building color of the monarch's wings and body shines through. In this picture, you can see where the butterfly's legs have pulled away from the outer shell, giving it a whitish look. Something's about to go down.

Liam was on fire. He kept a close eye on Combo all through the predawn hours as we got ready for school.
Much as we willed it to be so, I knew that Combo wouldn't emerge before the bus came for Liam at 8:05.

So we made consolation pancakes, and Liam got to flip them. This one is just about ready to flip.Go Shoomie, go!

Well done, Chef Shoom.
Finally, the time came to take Liam to the bus. I drove down the driveway, holding Combo on his twig aloft in one hand while negotiating the bumps and curves. I didn't know when he might hatch, and I wasn't going to let him out of my sight for a moment.
Liam and I took Combo on the bus to show the kids, he knowing that the chrysalis would be a butterfly by the time he came home that afternoon. It would be three more hours before the butterfly emerged, and I fought with myself the whole time. Should I have kept them home to see this miracle, this thing that means so much more than math and social studies?

Yes. I wish I had kept them here to see it.

Like crazy.


The photos in the ensuing posts will have to suffice. There will be other summers and other monarchs, but this one was special.

We await the new monarch.

Shape-Shifting Chrysalis


Perhaps unaware that its skin has popped off, the chrysalis continues its wild loops. Perhaps it's just exulting in the last motion it will be able to execute before it hangs, motionless but transforming, for the next 14 days.
You can see its beaded antennae, running from the eye (at the bottom of the chrysalis) along the leading edge of the wing. You can see the veins in the wing, and the segments in its fat abdomen.

Here's a sequence of pictures that shows how the chrysalis changes its shape in the course of only an hour. It starts out still vaguely cylindrical, reminiscent of a caterpillar.
It writhes and pumps and changes as it hangs.The whitish line on its midsection moves up as most of the bulk moves higher into what will be the butterfly's abdomen. It's starting to assume the tapered shape of a mature chrysalis. (see the right-hand one for comparison).

But for the ravishing seafoam-green color, the fresh chrysalis on the right is almost there:
Over the next day, the whitish buttons on the midline and around the tip will brighten to burnished, 24 K gold finish. I don't understand or know how an insect creates the hue and sheen of iridescent gold, but it does, and I am in awe.

We let this caterpillar choose a place close to another chrysalis to hang and make its transformation. However, at this point it's possible to detach the silk anchoring the chrysalis with a sharp X-acto knife, and with a dot of Elmer's glue, attach it wherever you wish. The important thing is that the chrysalis hang absolutely clear of any obstruction such as a twig or terrarium side. The emerging butterfly is weak and must hang clear of obstacles, or its wings could dry crumpled, rendering it flightless. So a thin twig is ideal for anchoring the chrysalis.
Here, the glue is drying. When it hardens, I'll hang the chrysalis up where it can get light and air, to remain undisturbed for a couple of weeks. I'll spray it with a mister from time to time, but that's about it. The chrysalis has work and much magic to do.

If you like these photos, just wait 'til you see what I captured this morning. We have a butterfly to look forward to!

A Caterpillar Sheds Its Skin

Down at the Monarch Ranch, the caterpiggles were gettin' fat, poopin' and eatin', poopin' and eatin'. When they get this big and fat, they'll soon go on walkabout, looking for a place away from the milkweed patch where they can hang themselves up, shed their caterpiggle skin, and burst forth as a chrysalis. You have to pounce on them when they get big and fat if you want to be part of the process. This'n's ready to harvest.
We bring them inside and install them in a small terrarium, where we put a fresh milkweed top in a narrow-necked vase of water to provide food. They eat like crazy for a couple of days and then wander around, finally pasting themselves to the top of the terrarium with silk. Here, the caterpillar is creating the liquid silk pad that will harden and suspend it for the next couple of weeks. The head end is to the left. It can be hard to tell with monarchs which end is which. I think the silk comes out of spinnerets in the rear end.

Once secure, the caterpillar hangs upside down in a J shape, waiting for the transformation to chrysalis. Slowly, the caterpillar's brilliant yellow, black and white skin becomes dull and translucent. The first sign that something's going down is when the antennae, normally mobile and responsive, get all limp and crinkled. See how the antennae on the head are just hanging here, no longer turgid?

Here, I must stop and give credit to Phoebe, who watched this caterpillar like a hawk, and kept it with her so she wouldn't miss the moment when it split its skin to emerge as a chrysalis. She noticed an undulating motion as the caterpillar hung there, and the skin started to stretch and pile up at the fastening point at the rear. Suddenly it split down the back like a pair of my old skinny pants.
From there, things progressed quickly, and the undulating wave of the chrysalis' still pliable body sent the skin rumpling up into a pile at the rear end of the creature.
Seeing this glorious, fantasmagorical thing emerge from the dulled skin of the caterpillar was awe-inspiring.
More and more stripes and abdominal segments are visible with each wriggle.I especially love the next shot, because Phoebe's sweet red lips are blurred in the background. At this point we're all whooping and hollering, and I'm frantically shooting around both kids' heads as they crowd in to see the miracle. Look at the blue, gold, and white stripes!! Who knew?

Now the chrysalis changes its dance, with the undulating wriggle becoming a wild spiral hula as it moves the skin up and off its body.In the picture above, you can see the proto-wings of the butterfly-to-be, folded like shields over its body.

A few more wild loops, and the skin pops off-ptoo! to land on the vinyl tablecloth, creepy legs, antennae, and jaw parts intact. The chrysalis won't be needing those jaws any more. Transformed to a sucking straw, they'll be. It's all too much, really, to try to describe or assimilate, too miraculous and bizarre. More anon.
