While trying to locate the Cyna Blue which would occasionally disappear, I found this surprise Boisduval's Yellow. Normally you have to travel to Resaca de la Palma or Sabal Palm in Cameron County to see the Mexican pierid. I thought it might take a while to get one if ever in our yard, butterfly #116.
Here's another Mexican Yellow. It looks a lot like the Boisduval's but is mostly off white above while the Boisduval's is bright yellow.
Tomorrow is scheduled to be hot and windy ahead of a front so stay tuned.
