The house angle spider ( Tegenaria domestica , syn .: T. derhami , T. domesticus ), also called cellar spider or " house spider ", is one of at least eight species of the genus of angle spiders ( Tegenaria ) from the family of funnel spiders (Agelenidae) native to Central Europe. .
The German common name " house spider " is commonly used for many spiders of the genus Tegenaria and related genera (e.g. Eratigena ), which are often found in houses. In addition to the house spider, these are:
- the wall angle spider ( Tegenaria parietina ),
- the rust-red angle spider ( Tegenaria ferruginea ),
- and the large angle spider ( Eratigena atrica , Syn .: Tegenaria atrica ).
The house corner spider Tegenaria domestica can easily be confused with other species of the genus. The drawing of the sternum should be used to differentiate .
Habitat and Distribution
The house corner spider Tegenaria domestica is likely to be found in all temperate climates in the northern hemisphere.
It lives mainly in houses close to people, in cellars, sheds, barns or empty buildings. In hard-to-reach and dark corners that are undisturbed for a long time, such as behind cupboards and in cavities, she builds her cave, which turns into a funnel, in front of which a woven carpet is woven with tripping threads. The house spider can also be found outside in sheltered places in summer, on piles of stones and walls.
Appearance
The females reach a body length of up to 11.5 millimeters, the males up to nine millimeters, but have longer legs that can reach a wingspan of eight centimeters. The light ocher to brown-gray body is lighter in color than in other species of the genus Tegenaria . The mark on the breast shield is constricted once in the middle, the four lateral spots vary greatly. The much more rounded abdomen only appears light brown to light gray at first glance, but also has a pattern similar to that of Eratigena atrica : the light "angular spots" are larger. The body is densely covered with soft hair. The hairy and bristle legs are indistinctly curled or spotted.
