This butterfly was trapped below the bird netting in our veggie garden. I handled it only briefly for these photos. It rested for a moment in my open hand before flying away.

Papilio troilus?
This looks more like a female spicebush swallowtail.

 
Sure is!
Female spicebush

Possibly
Female Eastern Tiger Swallowtail Black form Papilio glaucus

 
Mimickry
Amazing, I thought it was at first, just by comparing photos, but then I drifted to Pipevine after reading the various description. What clinches the ID?

 
definitely a Spicebush.
Check out the guide images at the bottom of the Black Swallowtail page; it's a great cheat sheet.
The short version: this butterfly has lacks the iridescence of the Pipevine, the black line zigzagging thru the blue patch of the black-form Tiger, and the yellow spots above the blue patch of the Black Swallowtail. This leaves only one contender: the Spicebush.
