## Appearance

The Diplolepis polita is a tiny, dark, and often shiny wasp, appearing somewhat ant-like with a compact body and clear wings. Its most distinctive feature is not the wasp itself, but the reddish, spiky, mossy galls it creates on rose plants, which are much larger than the insect.

## Taxonomy

- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Insecta
- **Order:** Hymenoptera
- **Family:** Cynipidae
- **Genus:** Diplolepis

## Interesting facts

- Female Diplolepis polita can lay eggs that hatch into more females without needing a male!
- The plant galls grow into a perfect, safe, food-filled house just for the tiny developing larvae!
- The spiky, mossy galls created by these wasps are sometimes called 'Robin's Pincushion'!
- These tiny wasps are so precise, they can make a rose bush grow a whole new structure!

## Special abilities

- **Gall Architect:** Diplolepis polita can chemically alter rose plants to grow protective, nutrient-rich nurseries for its young.
- **Tiny Engineer:** Diplolepis polita has a specialized ovipositor that precisely injects eggs and chemicals into plant tissue.
- **Hidden Nursery:** Diplolepis polita larvae can develop safely inside the plant galls, protected from many dangers.

## Measurements & details

- **Wingspan:** 3-6 mm
- **Size:** 2-4 mm
- **Lifespan:** 7-14 days
- **Leg Count:** 6

## Diet & Feeding

The larvae eat rose plant cells while adults may sip nectar from various flowers.

- **Age differences:** Larvae consume plant tissue within galls, while adult wasps may feed on nectar and pollen.
- **Primary Foods:** Rose plant cells, Nectar, Pollen
- **Foraging Method:** Foraging

## Ecological connections

- **Depends on:** Dog Rose (*Rosa canina*) — Host plant for gall formation.
- **Parasitizes:** Gall Wasp Parasitoid (*Orthopelma mediator*) — Lays eggs inside Diplolepis larvae.
- **Eats:** [Great Tit](https://www.snappit.app/explore/great-tit) (*Parus major*) — Birds may predate on larvae in galls.

## Safety

**Danger:** 1/5 · Very low

It's best to look at the galls but not touch them, as they are homes for tiny insects.
