Western Tiger Swallowtail on a Western Wallflower

All original art is hand-drawn by me, scanned by me, and digitally-colored by me based on my own photo references collected during my fieldwork as a biologist. Most of my work comes in three versions:

  • The original pen-and-ink drawing - a classic format used for centuries to illustrate books and other print publications. 
  • The color version - a digitally "painted" version of the original artwork.
  • An infographic version - another version of the color artwork, which includes a range map and natural history information for the listed species.

In addition, each version has two or three button links.

  • Purchase prints - goes to my artist site at, which is powered by FineArtAmerica, a high quality print manufacturing and order fulfillment service. Here you can buy framed and unframed prints in different sizes and on different papers, as well as other items such as mugs, blankets, pillows, etc.
  • License this image - goes to the page for this image at, where it can be licensed for commercial use.
  • Digital download - for infographics only. This goes to my Etsy store where you can purchase a high resolution file for personal use. Educational use is also acceptable (excellent for school teachers!)

This illustration of a Western Tiger Swallowtail (Papilio rutulus) on a Western Wallflower (Erysimum capitatum) was completed on October 20, 2017. The drawing is based on a photo I took on Mt. Waterman in the San Gabriel Mountains of the Angeles National Forest, Los Angeles County, California earlier in the year. 


The Western Tiger Swallowtail is a common butterfly of western North America. Its wingspan is 3 to 4 inches (7 to 10 cm). The adults feature yellow wings with black stripes and blue and orange spots near the tail. They are found in a wide variety of habitats, including forests, meadows, riparian areas, parks, and urban gardens. It's eastern counterpart, the Eastern Tiger Swallowtail (P. glaucus), is similar in appearance and habits.
