Your letter to the bugman:  Daniel, I thought this leucistic Variable Checkerspot butterfly I photographed 6/14/19 might interest your readers.  I’m including typically marked checkerspots for comparison.
Cheers,

Leucistic Variable Checkerspot

Dear Dwaine,
We needed to research the term “leucistic” before we could address your submission, and we learned on Merriam Webster that leucanism is “an abnormal condition of reduced pigmentation affecting various animals (such as birds, mammals, and reptiles) that is marked by overall pale color or patches of reduced coloring and is caused by a genetic mutation which inhibits melanin and other pigments from being deposited in feathers, hair, or skin.”  In continuing our research, we found there are no examples of leucistic Variable Checkerspots on BugGuide, nor is there any mention in Jeffrey Glassberg’s Butterflies Through Binoculars The West.  We are thrilled that you have allowed us to publish your images, and also thanks for including an image documenting the normal variations of the Variable Checkerspot,
Euphydryas chalcedona.
