Moths

First, all of these moths are dead.
Jimmy found them close to the brick plant and brought them to me.

The first one looks like a Columbia Silkmoth to me.

The other two I don't have a clue.
Notice the camouflage appearance of the last one.

If interested, watch for Hap's comment,
because I think he will come and id them for us.

Underside of all 3.
Look how much larger the first one is.

Update: The first one is a Cecropia Moth, the second one is a female Dobsonfly, and the third one is a Pandorus Sphinx Moth. Thanks for all the comments.
