Explanation of Names
The recently coined common name "Variable Checkerspot" was created to cover the lumping of E. anicia into E. chalcedona, which resulted in an indeed highly variable hodge-podge of different looking insects all bearing one species name.

The older common name, and more appropriate is the "Chalcedon Checkerspot".

The common name "Colon Checkerspot" was based on one of the subspecies of E. chalcedona, but that particular name was often widely used beyond the range of the particular subspecies.

Additional common names that are sometimes published are based on other of the regional subspecies names.
