Island Marble Butterfly
A small white butterfly with green marbled undersides found only on San Juan Island, Washington. It was presumed extinct for 90 years before rediscovery in 1998.
Did You Know?
When rediscovered, it was initially mistaken for the common Sara orangetip butterfly.

Did You Know?
The seasonal colour change is triggered by day length during the larval stage, not temperature.
