Does anyone know what this is called? I found it hanging around my yard.
Hornworm? Or what?
White-lined Sphinx, Hyles lineata

Cool! Thank you for looking that up! I first saw it by a patch of the Pink Evening Primrose (which is mis-named, since it stays open during the day), so apparently it was using that for food. And I've definitely seen the adult moth too!
You're welcome! Yes the adults are great but the larvae aren't too popular... it's amazing how different they can look!
Take a look halfway down this page:

If you want to, Bug Files could use another picture of the larvae, just click on 'upload an image' on its page
