Swallowtail on a Wallflower
The 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.
Great photo of one of our larger very beautiful Western Tiger Swallowtail, Papilio rutulus rutulus.
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!
Thanks, Michelle. I’m really looking forward to our Herb and Butterfly Walk on Sunday, May 19.
