Submitted by: Geoff Urwin
Specimen type: Photograph
Observation notes: Saw two that day in different locations. This is the only one I got a photo of. It was first on an emergent Aspen leaf as you see in the photo, and then on a Thistle flower. Black line crossing the veins distinguishes this species from the very similar looking Monarch butterfly.
