Amaurobius genus, a part of the tangled nest spider family, has a wide range, spreading across Europe, Asia, and the United States.
Size: The average size of several spiders of this genus can span from 0.19 to 0.78 inches (5 to 20 mm).
Color: Their colors vary from light to dark brown. For instance, the black lace-weaver (Amaurobius ferox), one of the prominent species of this genus has a brownish-tan appearance.
Other Characteristic Features: Most of them have a rounded abdomen with a striped pattern on their legs. Species like the Amaurobius similis, and Amaurobius fenestralis both referred to as the lace-web have v-shaped abdominal markings.
The females of several Amaurobius spiders make a white sac where the small-sized eggs remain safely encased.
There is not enough data on how spiderlings survive but most of them disperse to be on their own in a month’s time after hatching.
These ground-dwelling spiders construct funnel-shaped or tube-like silken webs mostly behind barks of trees, fences and buildings,
Most spiders of this genus like the lace-webbed spider (Amaurobius similis) are infamous for their painful bites particularly if provoked. However, their venom is not known to cause any serious medical problems.
| Distribution | Germany, Switzerland, Greece, Italy, Turkey, Libya, China, Spain, Argentina, Micronesia, France, Italy, and USA |
| Habitat | Forests and grass lands |
| Diet | Insects |
