## Appearance

## Taxonomy

- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Insecta
- **Order:** Diptera
- **Family:** Bibionidae

## Interesting facts

- Bibio larvae can live underground for up to a whole year before transforming into adults!
- Even though many Bibio fly in spring, some unique species emerge to fly in autumn instead!
- Male Bibio often swarm together, looking like tiny flying clouds in the spring!
- Some Bibio species are called 'hawthorn flies' after their favorite springtime plant!

## Special abilities

- **Spring Swarmer:** Bibio males can gather in huge aerial swarms because this helps them find mates quickly during their short adult lives.
- **Underground Cleanup Crew:** Bibio larvae have strong mouthparts that help them break down dead leaves and plants in the soil, enriching it.
- **Early Bird Pollinator:** Bibio adults brave cool spring weather to pollinate early flowering plants that other insects might miss.
