COSEWIC Assessment and Update Status Report on the Island Marble in Canada
The Island Marble, an undescribed subspecies of the Large Marble, Euchloe ausonides, was thought to be a Canadian endemic that was historically found on Gabriola Island and Vancouver Island from Nanaimo in the north southward along the eastern edge of Vancouver Island to Beacon Hill Park, Victoria. It was recorded only at lower elevations. Nothing was ever recorded about its larval foodplants. Elsewhere in the species' range, the larvae of other subspecies feed on wild crucifers of the genus Arabis which occur on Vancouver Island and are also a larval food source for the related species, Sara's Orangetip, Anthocharis sara (Lucas, 1852). Sara’s Orangetip has a much wider altitudinal range on Vancouver Island than the Island Marble and is still found on steep hillsides.
