Pale Swallowtail
Papilio eurymedon

Observation date: June 08, 2018
Submitted by: magnolyah
Specimen type: Photograph
Observation notes: sunny day - very warm
Status: Resident
Verified by: A_baldini
Verified date: August 28, 2018
Coordinator notes: Correct identification. In photographs, faded Western Tiger Swallowtails can sometimes resemble Pale Swallowtails, especially depending on the lighting, but the thicker "tiger stripes" on the Pale Swallowtail separate the two. In Colorado, this species is most abundant in mid-June, usually in canyons (like where you saw this one).
