Euchloe olympia, the Olympia marble, is a butterfly in the family Pieridae. Its range is southern Canada and the Midwest, down into the southwestern United States.[1] E. olympia is related to E. guaymasensis, but has a distinctive phenotype and genotype.[2]
Euchloe olympia has been observed to use Lepidium virginicum as its main nectar source as a larval and as an adult the main nectar source was found to be Nuttallanthus canadensis. Based on a study done in a central Illinois sand prairie, Echloe olympia was observed to show consistency on the flowers it visits to obtain its nectar from.[3]
The Olympia marble has been classified globally as G5/G4, meaning that globally it is a relatively stable species. The United States has not placed it under any watch as a country. However, it is in danger due to gypsy moth chemical control.
