Took this in the NW corner of Connecticut. At first we thought it was a Red Spotted Purple, but on close look it isn’t. A transiting Black Swallowtail perhaps?

Dear L. Welles,
This Spicebush Swallowtail, Papilio troilus, which you may read about on BugGuide, appears to be missing its signature tails, or perhaps they are just hidden in the tall grass. We are happy you submitted photos showing both the upper wing coloration and markings as well as the lower wing markings and coloration.
