What is the name of the butterfly or moth species that appears to have a skull?

From the text:

“This is the Death’s-head Moth,” he said. “That’s nightshade she’s sitting on—we’re hoping she'll lay.”

The moth was wonderful and terrible to see, its large brown- black wings tented like a cloak, and on its wide furry back, the signature device that has struck fear in men for as long as men have come upon it suddenly in their happy gardens. The domed skull, a skull that is both skull and face, watching from its dark eyes, the cheekbones, the zygomatic arch traced exquisitely be- side the eyes.
