What's That Bug? does not endorse extermination

This moth was found sitting on the wall outside of our garage early this morning (4/22/12) in Escondido, Ca. It is a very large, brown moth and it has eyelash like antennas. It hasn’t moved at all today. I have researched online and cannot seem to figure out what species it is. If you can help, that would be great!

Polyphemus Moth

Hi Kaylynn,
This is a male Polyphemus Moth.  The feathery antennae indicate his sex since he used his antennae to sense the pheromones of the female.  Polyphemus Moths are found coast to coast across North America, but west coast sightings are not as common as sighting in the eastern part of the country.
