Synonyms: Hodges #4202.
The Olympia Marble (Euchloe olympia) is a rare denizen of open habitats where its preferred host plants can be found, like shale barrens or lakeshores. In our area, it is restricted to shale barrens of western Maryland. This interesting and strikingly-marked butterfly is on the wing early in spring, from March into the middle of May in Maryland (Butterflies of Maryland: A Biological Summary and Checklist by Lynn Davidson & Richard Smith; Kaufman Guide to Butterflies of North America). Its restricted range and uncommon habitat make it vulnerable to extirpation, and it is ranked as S2 (state rare).
Olympia Marble primarily utilizes rockcresses as larval food plants.
There are 80 records in the project database.
