Found this very beautiful but very lethargic moth on my front doormat this morning. Is it a cecropia moth? Furry body and antennae are feathery. It was also very large!

Male Polyphemus Moth

Hi Trixie,
This Polyphemus Moth is a member of the Giant Silkmoth family like the Cecropia Moth, but it is a distinctly different species.  You can tell your Polyphemus Moth is a female because of the shape of her antennae.  The are not as plumose or feathered as the antennae of the male Polyphemus Moth.

Ed. Note:  Thanks to a comment, we inspected the antennae more closely and we now agree that this is a male Polyphemus Moth.

    That’s definitely a male Polyphemus.

      We were deceived by the low resolution of the image and the blending of the antennae into the rug. Upon closer inspection, it is possible to the the plumose structure of the male’s antennae. Thanks for the correction.

    Found one of these in Kerrville, TX this morning. An exact match of the picture of a male. Such a beautiful little life and the antennae look exactly like a tiny leaf!
