Observation notes: Wow! I can't believe an Eastern Tiger Swallowtail was in my flower garden... this late in season, plus
way North ...out of its range . in 20 years of living up here and 12 years of "On the Hunt" for the North woods butterflies. I
have never ever seen an Eastern Tiger this far north..... Is this a record? .. It was feeding on zinnias like it was starving, and flying around my garden ...so cool

Coordinator notes: Agree...this is pretty far north for the species, however not the furthest north I've seen reported/verified. Probably strayed northward like many other species this summer. It could also be a hybrid/intergrade between the P. glaucus (Eastern) and P. canadensis (Canadian), which can be seen in later summer in the transition zone between the two species. There is still ongoing taxonomical work attempting to clarify. The ventral FW submarginal yellow spots appear separated, c/w P. glaucus. Also, the ventral HW trailing edge/anal dark line is very thin, c/w P. glaucus. The ventral HW submarginal/postmedian dark line between the black and yellow is less "scalloped" and more straightened appearing, and the submarginal orange spots are more rectangular than crescent, c/w P. canadensis. Long story short - possibly a mix - but I'm still leaning towards P. glaucus. Definitely too late for a pure P. canadensis. -jmgesell
