Even BAMONA can't tell the difference between male Juvenal's and Horace's Duskywings. That's what they said on one of the last pictures I sent them. So I just call them Duskywings.
Ann, that's so great to see Black Swallowtails on a native plant! Thanks for adding to the database. The Black STs still haven't found me, but I'll be busy with Spicebush cats soon, so I'll just deal with one thing at a time.
