Submitted by: steepdeep
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: August 18, 2011
Coordinator notes: Female on Thistle flower. The sun is shining thru the wings so brightly it they look very white. The abdomen shows faint yellow so this also could be Papilio rutulus. The two are similar in markings except the latter is of course one of the yellow tiger swallowtails.
