About

Purpose:

The purpose of the website is to help with the identification and recognition of different species of butterflies, particularly those found in Starr County, TX. The website is owned and maintained by Berry Nall. I am solely responsible for all content, including errors. I am an enthusiast and not an expert, so mistakes are likely. Please notify me of any misidentified pictures or other issues with the website.
