Overview
Euchloe ausonia, the eastern dappled white, is a southern European and Palearctic butterfly found mostly to the south and east of its almost indistinguishable relative the western dappled white.
The Eastern Dappled White faces significant threats from habitat loss and fragmentation as agricultural intensification and urban development reduce available calcareous grasslands and rocky slopes. Climate change poses additional risks by altering the distribution and phenology of its cruciferous host plants, while the species' specialized habitat requirements make it particularly vulnerable to environmental changes.
Habitat
Inhabits dry calcareous grasslands, rocky slopes, scrublands, and limestone hillsides typically between 200-2000m elevation. The species requires areas with abundant cruciferous host plants, particularly wild candytuft and other Iberis species, along with nectar sources for adults.
