Feeding Swallowtail

Pipevine Swallowtail -- Putah Creek, CA
Canon EOS Rebel T5i, EF 100-400mm f/4.5-5.6L IS II USM, ISO: 2500, f/5.6, 1/1600s

Another of many swallowtail shots from Saturday.  This is one of dozens of pipvines that I saw on that drive through the hills around Lake Berryessa and Napa Valley.  The wings are blurred by movement.
