Observation notes: This dark swallowtail had a single band on 7 bright orange spots below. Above, it was plain, with a band of whitish spots near the edge. In the right light, it had a greenish sheen above on the hindwings. It appeared to be a female. It fed on Mexican Zinnias. For a few moments, it settled quietly on a dogwood leaf, only about a foot from a Pipevine my wife planted (its host plant), though it was not clearly laying eggs. We got a poor photo of one here in 2017, the only other time I've seen one in Columbia.
