Nuctenea umbratica (Clerck, 1757) – Walnut Orb-weaver, Dentyback spider, Crevice spider, Gap spider

Occurrence: Nuctenea umbratica is common in the forests, in the fences, in the buildings and in the gardens. It is a very abundant species. We often find the spiders close to each other. Description: The abdomen is flattened, black folium can have white trim. Adult females can grow to about 14 mm. Period of occurrence: The spiders occur throughout the year. Web: The big web looks it is built sloppy, also it is not strong. The spiders hide in building or fence crevices or under the bark of trees. They respond to a prey usually later. Signal thread is usually not significant. During the day we don´t find these Orb-weavers sitting on the web. Food: Their food is small flying insects.
