Spicebush Swallowtail (not “Pipevine Swallowtail II”)

I posted an image of a Pipevine Swallowtail last year — http://365project.org/rhoing/365/2011-06-19 — but that was of the more colorful undersides of the wings. Today this specimen was posing for me for a long time with wings open!

[Eeeeeeh] Wrong apparently! The regional coordinator at BAMONA — http://www.butterfliesandmoths.org — confirms this as “Papilio troilus” or “Spicebush Swallowtail”; http://www.butterfliesandmoths.org/sighting_details/728885

In my defense, one of my field guides has the following on the Spicebush Swallowtail: “… Edible mimic of distasteful Pipevine Swallowtail.”

At BAMONA, this description of the
» Pipevine Swallowtail: “Upper surface of hindwing iridescent blue or blue-green” — http://www.butterfliesandmoths.org/species/Battus-philenor
» Spicebush Swallowtail: “Upper surface of forewing is mostly black with ivory spots along margin. Upper surface of hindwing has orange spot on costal margin and sheen of bluish (female) or bluish-green (male) scales” — http://www.butterfliesandmoths.org/species/Papilio-troilus

Since my specimen’s scales seem to be bluish, I'm guessing this one is a female.
Thank you again, Roger!

Update. This image is on the BAMONA species page for this species, http://www.butterfliesandmoths.org/species/Papilio-troilus

@myautofocuslife Thanks, Livia! S/he was resting in a few shaded places. I couldn't always see "in" to where it was, but it was easy when I could!

@digitalrn Indeed, she does, Rick!

@jtookey150 Thank you, Jean. The swallowtails are definitely captivating!

@xtech Thanks so much, Elaine! Yesterday was quite a day in the garden. There was a pair or more of hummingbird moths and a pair of hummingbirds as well. The hummingbird images weren't very good; certainly not as good as this!

[Jill]

What a gorgeous butterfly!

[Elizabeth Youngs]

Beautiful capture! I love the composition and details!

[Michelle]

Amazing detail Thom

[Carolyn White]

Beautiful capture!

[Lisa Pouncy]

Gorgeous. I love the smattering of blue glitter on its wings xx

@cjwhite Thank you, Carolyn! And according to the regional coordinator at BAMONA (Butterflies and Moths of North America [dot] [org]), this is not another Pipevine Swallowtail, but rather a Spicebush Swallowtail (Papilio troilus). Sigh — I thought this one was a slam-dunk Pipevine.
