## Appearance

The Phantom Hemlock Looper is a small, pale moth with mottled grey and brown wings, resembling tree bark. Its forewings often have faint, wavy lines and a small dark spot, making it blend seamlessly with its coniferous forest home.

## Taxonomy

- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Insecta
- **Order:** Lepidoptera
- **Family:** Geometridae
- **Genus:** Nepytia

## Interesting facts

- Adult Phantom Hemlock Loopers have such short mouths they usually don't eat!
- Female moths release special scents to attract mates from far away!
- Its caterpillar stage is called a 'looper' because of how it moves!
- This moth uses incredible camouflage to hide from hungry predators!

## Special abilities

- **Bark Camouflage:** Phantom Hemlock Looper can disappear against tree bark because its mottled wings perfectly mimic its environment.
- **Looper Locomotion:** Phantom Hemlock Looper larvae can move in a distinctive 'looping' motion, allowing them to navigate branches efficiently.
- **Sonic Stealth:** Phantom Hemlock Looper has specialized scales on its wings that help it absorb sound, making it harder for bats to find.

## Measurements & details

- **Wingspan:** 30-45 mm
- **Size:** 20-35 mm
- **Lifespan:** 300-365 days
- **Leg Count:** 6

## Diet & Feeding

Young loopers eat conifer needles, while adult moths typically do not feed.

- **Age differences:** Larvae feed on conifer needles; adults are non-feeding or drink dew/sap.
- **Primary Foods:** Tsuga heterophylla, Pseudotsuga menziesii, Abies grandis, Picea sitchensis
- **Foraging Method:** Foraging
