Camouflaged looper inchworm

On July 13 in the mass of black-eyed susans, I spotted more than a dozen different kinds of insects. The coolest was this one, which I believe is a camouflaged looper inchworm. Its destiny was to turn into a wavy-lined emerald moth.

Black-eyed susan with a small caterpillar at the top of the center disk, with lots of dark brown spikes sticking off its body.

This caterpillar chews off parts of plants and then attaches them to itself as a disguise.

Flower from above, with a caterpillar looped on the left side and several brown clumps attached to its body.

It was concealed so well against the flower’s dark-brown center disk, I’m not sure how I even spotted it at first!

Angled view of a flower, with a small brown clump on the opposite side of the center disk.

Though after I saw it once, I could easily find it again later the same day, and even the next day. (The accumulating quantity of frass also helped locate it.)

Caterpillar with its front end raised above the center disk.

Making its way around the ring of tiny flowers in the center disk of the black-eyed susan:

Side view of the flower, with a caterpillar on the right side, the back half of the center disk's flowers missing.

Almost finished the next day:

Side view again, caterpillar on the left side, no center disk flowers visible, but the caterpillar still appears to be eating.

I saw it crawling around a bit but unfortunately didn’t get to see any of the actual “gluing.”

Two more videos:

I kept checking back for this inchworm every day for a week and saw it many more times.

Top view showing two thick layers of camouflage:

Only the very top of the caterpillar showing, with two distinct ridges of material on its body.

Sometimes it was resting on a petal, and in these cases it looked nothing like a caterpillar.

Once I thought it was gone, but then found it again on a nearby flower. This time it looked different after it apparently re-covered itself with new material.

Flower in shade apparently underneath another flower, with the caterpillar 'inched' and some lighter brown or yellow material on its body in addition to the dark brown.

And this time I saw it eating the petals, too.

Caterpillar on a petal that's curving down, reaching out to the edge.

But after that, I didn’t see it anymore. Hopefully it made its way safely to its next stage as a cocoon.
