- Their scientific name, 'or', comes from the 'O' mark on their wings!
- This moth can have two generations in one year, meaning twice the moths!
- Wow, they spend most of their life as a caterpillar, munching leaves!

## Special abilities

- **Master of Disguise:** Poplar Lutestring has forewings that perfectly mimic bark patterns, helping them blend seamlessly with tree trunks to hide from predators.
- **Night-Time Navigator:** Poplar Lutestring can sense bat echolocation using special ear organs, allowing them to take evasive action and avoid being caught.
- **Scent Whisperer:** Poplar Lutestring uses invisible chemical signals called pheromones to attract mates across distances, ensuring they can find each other.

- **Wingspan:** 33-38 mm
- **Size:** 15-20 mm
- **Lifespan:** 7-14 days
- **Flight Speed:** 5-10 km/h

- **Primary Foods:** poplar leaves, aspen leaves, willow leaves, birch leaves
- **Foraging Method:** Grazing

## Ecological connections

- **Depends on:** European Aspen (*Populus tremula*) — Its caterpillars feed on the leaves of this tree.
- **Depends on:** Goat Willow (*Salix caprea*) — Another key food source for caterpillars.
- **Hunts:** Noctule Bat (*Nyctalus noctula*) — Bats are major predators, catching adult moths.
- **Eaten by:** [Eurasian Blue Tit](https://www.snappit.app/explore/eurasian-blue-tit) (*Cyanistes caeruleus*) — Young birds feed on the protein-rich caterpillars.
