Scientific name: Araneus angulatus (Clerck, 1758) Common name: French name: Épeire à dents de scie, Épeire anguleuse. Order: Araneae Family: Araneidae Size: Body size : 12 to 15 mm for females, 10 to 12 for males. Biotope: Forests, woodland edges, clearings, parks and gardens. Web: Large size orb web, up to 70 cm, but with only 20 to 25 radials. The spider eats its old web just after nightfall and immediately spins a new web. The webs you can see during the day are always very damaged. Observation period: You can observe adults from June-July. Geographic area: Palaearctic region. |
Araneus angulatus is used to resting in a hide during the day and only comes out after nightfall. You can tell this species apart with the saw tooth pattern, with a regular triangle shape, on the upper side of the abdomen. It has also two typical tubercles on each side of the abdomen. There is a possible confusion with Gibbaranea gibbosa, however the saw tooth pattern you can see on this last one resembles more small points. It is well triangle shaped on Araneus angulatus. Furthermore, Gibbaranea gibbosa is a smaller size. |

Every evening, just after nightfall, this spider was used to spinning its web in front of the open window of the garage. I have first thought to Zygiella x-notata because of the location and because the damaged web, observed in the morning, was missing some sectors. Though a violent flash light, you can still see the saw tooth pattern on the abdomen and the tubercles on each side. The large side of the body also confirms this spider species. |
