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.
Solomon's Seal Sawfly
A small, entirely black sawfly whose grayish-white larvae with black heads are highly destructive to Solomon's seal plants. Larvae feed from the leaf edges inward.
Did You Know?
The larvae are so well camouflaged against the undersides of Solomon's seal leaves that gardeners often only notice them after severe damage is done.
