Woolly Alder Sawfly
A small, dark sawfly whose larvae are covered in a white, woolly, waxy secretion. The larvae feed on the underside of alder leaves.
Did You Know?
The white waxy covering on the larva closely resembles woolly aphids, a possible case of defensive mimicry.
Common Nawab
A large butterfly with pale green-white wings edged in black with two prominent hindwing tails. It has a powerful fast flight and is rarely seen feeding on flowers.
Did You Know?
Instead of flowers it feeds on rotting fruit, tree sap, and animal dung using its proboscis to probe wet surfaces.
