Rosy Underwing
A large moth with camouflaged grey-brown forewings hiding vivid rosy-pink and black hindwings. When disturbed, the flash of pink confuses predators as it drops from its perch.
Did You Know?
Like all underwing moths, it uses a startle display, flashing its bright hindwings then vanishing as it re-covers them.
Dusky-winged Fritillary
A small fritillary butterfly with dark brown wings bearing orange spots and complex underside markings. It flies in remote mountain passes and high tundra. The species is named after Mount Natazhat in Alaska.
Did You Know?
This butterfly is so restricted to high-altitude Arctic habitats that each mountain population may be genetically distinct.
