Two-tubercled orb-web
Named for the two blunt humps on its abdomen, this orb weaver can shift between whitish, yellow, brown and near black depending on the individual.
| Where | Sunny shrubs and low vegetation |

| Size | Female 6.2 to 10 mm, male 4.8 to 8 mm body length |
| When | March to June and September to October |
The rounded abdomen carries two small tubercles that point out to the sides rather than upward, and its color is highly variable, running from whitish or yellow through light brown to almost black. The front of the body is dark brown.
It builds its web low among herbs and bushes in warm, sunny spots, often close to the ground, and is recorded more often toward the warmer parts of its European range than in cooler areas.
