- **Phylum:** Arthropoda
- **Class:** Insecta

## Interesting facts

- A single female moth can lay over 100 tiny eggs on tree branches.
- Male moths find mates using special scent detectors on their feathery antennae.
- Their caterpillars are considered pests in orchards, munching on fruit trees.
- They emerge as adults in late autumn and winter, defying the cold!

## Special abilities

- **Winter Flight:** Winter Moth males can fly in freezing temperatures because their bodies produce natural 'antifreeze' proteins.
- **Wingless Wanderer:** Female Winter Moths have tiny, useless wings and must crawl to find mates and lay eggs, unlike males.
- **Tree Bark Blending:** Their mottled wing patterns help Winter Moths hide perfectly on tree trunks, protecting them from hungry birds.
