Western Tiger Swallowtail

This spring we watched a plethora of Western Tiger Swallowtails flit through the garden. Males fly back and forth searching for receptive females. They rarely perch, and, when they do land, it is but briefly. This behavior makes them hard to photograph. This image was captured on 3 July 2019. As the name implies, Western Tiger Swallowtails are found across much of the West, from British Columbia to North Dakota, south to Baja California and New Mexico. The Eastern Tiger Swallowtail, a larger butterfly, replaces it in the East. There is one flight from June through July. The western species spends the winter as chrysalids.
