Flutter, sip ... flutter sip ...

Kind of like bar hopping?

Wonder if different colors have different flavors of nectar?

 

I got help in identifying it from the Google group,

sci . bio . entomology . lepidoptera,

with the answer being ...

Female Eastern Tiger Swallowtail, melanic form. Papilio glaucus.

Which is clear enough, except for "melanic form," a

new one for me. Upon looking up that term, I found that it means

an excess of black or nearly black pigmentation, and is

the opposite of albinism.
