Raising Butterflies

This post will confront my insanity, and provide some insight into raising monarchs and swallowtails. I hope. Did you all get my thesis statement? I hate thesis statements, and refuse to let my students use them, by the way.

I did not expect a banner year for monarchs (around 80 so far, with peak migration Sept 8-20 in Nebraska)--they are a threatened species in my mind (read my article on them here.) But I also have been bringing in monarch eggs religiously. Monarch eggs are often on the underside of milkweed leaves, though I have seen them on top and within blooming milkweed flowers, as well as on seed pods. They are little sesame seed-sized white / cream things that look like bullets. I've found that raising monarchs from eggs is easy, whereas for black swallowtails it's best to let them get going a bit outside through the first 2-3 instars (swallowtail eggs--on fennel and parsely most often--are yellowish balls of similar size to monarchs).

So a few weeks ago I bought a used 10g aquarium and did this to it:

You can see there are a FEW monarchs and swallowtails in there (30-40). Bottom is lined with paper towel. Picked up a fitted screen for the top at a pet store that I can easily lift off.  Gathered twigs from beneath my elm. Went CrAzY.

A monarch just went, you can see his twisting, long chrysalis in the middle above. Monarchs tend to cluster near one another as they form their chrysalis--if your friend pupated off a cliff, would you?

This weekend 11 monarchs got their chrysalis on, and today 4 did within 15 minutes of one another, and 3 more will soon go. (Also notice the brown swallowtail chryslides on the top right.) It's easy to tell when monarchs are about to shed their skin (not so easy with the slower swallowtails), look at this guy:

See his shriveled skin and antennae? The line on his side? (or her) I love seeing that skin slide up and off:

This monarch (below) attached to the side, and has a flat dent. Rumor has it things will work out. We will see:

And here's a closeup of a swallowtail. They secure their bums, too, like the monarchs, but also make a sling for their upper body to recline in:

And here is my assembly line:

Container 1 has monarch eggs on leaves. Container 2 very very tiny monarch cats (they will eat the eggs if you don't move them out). Container 3 and 4 are 2nd to 3rd instar cats. Container 5 holds small swallowtails. And then the 2g aquarium with a few more monarchs about to go.

It's overwhelming, and I've bitten off more than I can chew (the cats eat so much food I head outside 3-4 times day, and the poop, my god the poop cleaned out every day or two!). But, I have to do something. I feel like I'm doing something more proactive than recycling or gardening.

Tachnid flies lay eggs in monarch larvae with a vengeance, and often the monarch "J"s up early, dies, and hangs limp as the tachnid fly larvae slides out on a slime thread. Swallowtails get carted off by wasps and used as incubation chambers. Maybe I just see a lot of my life in this whole process (take that any way you want).
