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.
Common Bagworm Moth
A small moth whose larva builds a distinctive portable bag from silk and plant debris that it carries everywhere. Adult females are wingless and never leave their larval bag.
Did You Know?
The wingless female mates, lays eggs, and dies entirely within the bag she built as a caterpillar.
