Swallowtail on a Wallflower

IMG_2704The butterflies are out and about. I saw 4 species yesterday on the Herb Walk on Potrero John Creek. Here’s an iPhone pic of a Swallowtail, probably Western Tiger Swallowtail (Papilio rutulus), on a Wallflower (Erysimum capitatum).  It could possibly be a Pale Swallowtail (Papilio eurymedon). I’m not sure but I know who would know — Michelle Dohrn — and she’s joining us a special guest for an Herb and Butterfly Walk on Horn Creek on Sunday, May 19.

  1. Could not be a pale swallowtail because black markings are not thick enough along the outer edges of the wings. These species tend to be a little more elusive. Thanks Lanny for posting!
