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.
