Euchloe olympia

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. E. olympia is related to E. guaymasensis, but has a distinctive phenotype and genotype.

Nectar source

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.

Conservation status

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.
