Fluttering replies in our natural conversation, both yellow and black-colored swallowtails augur the coming of summer on Little Crum Creek.

They follow a season of cabbage whites, red admirals, and eastern tailed-blues that’s been brightly punctuated by the occasional question mark (Polygonia interrogationis) settling on a sunny weed or vine.

Otherwise quite similar to the comma butterfly, this one is named for two white or silver spots resembling a question mark on the bottom side of its hind wing.

(Considering the close resemblance of commas and question marks, I welcome any confirmation or correction of this ID.)
