Hummingbird Moths, Sphinx Moths or Hawk Moths Dear Mr Bugman,
I received these pictures asking me if it was an Atlas moth, is it or is it a "humming bird moth"? It was found at the Umatilla Chemical Demilitaration Facility on the Umatilla Chemical Depot in Hermiston Oregon. The specimen was released after the pictures were taken. Thank You,

Hi Don,
Your indiginous moth appears to be a Western Poplar Sphinx, Pachysphinx occidentalis, which is found from Western Canada to Baja California. We are going to seek the advice of Bill Oehlke as well as copying him on this response since he is compiling comprehensive data on species sightings.
Confirmation: from Bill Oehlke
Daniel, Pachysphinx occidentalis from Hermiston, Umatilla County, Oregon. Norte distinct am line which is blurry in modesta. Modesta also tend to have more of a blue grey colour while occidentalis is yellower. They are tricky to tell apart. Both fly in Umatilla County.
