I was inspecting my three hibiscus plants when I spotted some signs of a visitor on the red one.
First, I noticed some eaten leaves.

Then some frass/poop scattered on the lower leaves. I even found a shed skin that the muncher left behind after molting.

I knew from the spikes on the skin that my favorite caterpillar was on the underside of a leaf.
I had to search carefully. Its sting is painful.

Here it is. The Saddleback caterpillar/ Sibine stimulea. Still snacking.
Its rear end looks like it has eyes, but the poop is evidence that this is not its face.

I love these spiky, mean, green things!
