Can any one out there identify this little guy for me? Spotted this afternoon fluttering around my yard (suburban Phoenix, AZ) in some distress. If it helps, the grey stripe is approximately a half an inch wide.
Update: Looks like it is a White-lined sphinx (Hyles lineata Fabricius, 1775). More information here. Thanks to Gene Goldring for making the id.
Yup, that looks like it. Many thanks.
I hope I didn't step on any lepidopterist toes. ;)
A good site to check for arthropod id is www.whatsthatbug.com
I had the same question a few weeks ago (I'm in Tucson). I even shot some video. See the entry at my blog.
