Jimmy found them close to the brick plant and brought them to me.
Notice the camouflage appearance of the last one.
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.
