I’m having another Wildlife Lover’s Moral Dilemma, but this time it’s of a different sort. Up until now, my love of butterfly caterpillars has known no bounds, and I’ve gone out of my way to plant larval host plants and create a Caterpillar Hotel and so forth. But today caterpillars have rained on my parade, and my beloved caterpillars have come back to bite me, or at least my precious flower favorites.

It’s been raining a lot lately, and so I’ve not been in the garden too much, grudgingly recognizing that the nutsedge and bermuda are taking over again in the meantime. But a glimpse out my bedroom window got me excited — blooms lower down on the tall Cinnamon Sunflowers meant I had a chance to take new photos of my dark red blooms. I rushed outside in a dry pause from the rain… to a horrible sight.

The first thing I saw from a mere glance was a mass congregation of black on the leaves of one of my yellow sunflowers. Caterpillars, and a lot of them.

Then my eyes opened wider. There were more on the plant next to that one. And on down the short row.

Then I was hit with the realization that they’d completely defoliated many of the leaves of the yellow sunflowers, to the point that I’m not sure whether there’s a future in sight for any of the already-struggling annuals.

In fact, I’m quite certain that two of the smaller plants are dead, or at least zombies. I hadn’t even shown a photograph of a bloom from the poor traditional flowers — I’d been waiting for them to get bigger. I felt such sadness.

And then, like a scene in a horror movie, I turned slowly to look at my Cinnamon Sunflowers, dread gripping my heart.

The first thing I saw was caterpillar poop, and a lot of it.

Ok, something’s eating my Cinnamon Sunflowers. Looks like a few caterpillars. At this point, I’m still thinking it’s ok — I knew the flowers were larval hosts. I accepted that.

But as I opened my eyes beyond the poop to the damage and destruction above, around, and beyond, my heart started breaking.

I have what I can’t seem to call anything else — an infestation — of literally hundreds of caterpillars of all sizes. I knew by the spines that there was a good chance they were butterfly caterpillars, but still… in those numbers?

Part of me wanted them to be something that I could consider pest caterpillars, so that my moral dilemma could be simpler to deal with and I could find a soapy bucket of water. But no, as near as I can tell, these are the larvae of the Bordered Patch Butterfly. At some point, I am going to have incredible numbers of chrysalises and several dead, once beautiful sunflowers. Was this gorgeous butterfly from just a few weeks ago one of the culprits?

Despite the destruction, I can’t bring myself to dispose of the caterpillars, or feed them to the birds, nothing. Must… love… caterpillars.

I can’t love the butterflies without supporting their eggs and babies. I guess I’m just going to have to watch them devour my plants and hope that the sunflowers, at least the larger ones, will recover.

I thought about moving the Bordered Patch caterpillars over to the Zexmenia, also a host plant. But that’s when I discovered hundreds of caterpillars were over there, too. My beautiful Zexmenia, already getting eaten up, too. Gah! It’s ok, Meredith, it’s ok… planted as a host plant. All good.

Here’s what I want to know: when exactly did these Bordered Patch butterflies show up laying eggs? And OH MY GOSH JUST HOW MANY EGGS CAN THEY LAY? Holy cow. And where are my beneficial predators now, now that I need some ecoystem balancing? Hello birds, stop feasting on my seeds and get yourself some live protein. Leave a few so there’s still a good population of butterflies, please. Why didn’t anyone tell me that Bordered Patch butterflies and their cousins are the rabbits of the butterfly world?!!!

According to some sources online, Straggler’s Daisy, or Horseherb, is a larval host plant for the Bordered Patch. I’ve got plenty of horseherb, so I did try moving some of the caterpillars over. They wouldn’t eat while I was watching, and then the rain came again, so I’ll have to monitor them for awhile before moving the rest over. Cross your fingers — there’s a glimpse of hope for the sunflowers if I can pull this off. I’m not holding my breath for too long, though, since so many other sites didn’t list the little groundcover as a favorite host plant.

Between the masses of caterpillars eating my CinnSuns and the masses of nutsedge and weeds abounding in my garden, I just want to cry. And yet, I’m so happy we’ve had rain — just an absolutely wonderful thing in central Texas during the summer. And I can still smile at the Gulf Fritillary caterpillars on the passionvine.

I saw one starting its chrysalis stage today — it’s a J right now — and I happily discovered a chrysalis hanging from a Mexican Redbud branch. (I also discovered a passionflower bloom in the redbud tree — that pesky vine has done it again!)

But overall I feel like I’m being tested, and I’m not sure whether I’m passing or failing. Passing as a wildlife lover with a high level of tolerance for munchers; passing as a butterfly grower. Failing as a gardener who wants beautiful, intact plants around; failing my new sunflowers. This isn’t my veggie garden– with my tomatoes, it was a war I had to engage in, those hornworms and stink bugs. Now the line in front of me is blurry. Should I be thinking of the crazy numbers of caterpillars as pests or be happy that I’m supporting more butterflies?

No worries, it’s still the latter. I just need to get used to this new concept of caterpillar quantity and re-evaluate my planting methods. Clearly I need more sunflowers so that my plants aren’t so easily overtaken. That will work, right? Learn to share, butterflies!

Hang in there, sunflowers. I know this is tough love from mama.
