Tegenaria is a genus of spiders belonging to the family Agelenidae, commonly referred to as funnel weavers due to their characteristic funnel-shaped webs. These spiders are part of the Arachnida class and are found in various environments across the Comunidad Valenciana, as well as broader regions in Europe and North America.

The species within the Tegenaria genus vary, but they typically have certain common features:

• Size: They are medium to large-sized spiders, with some species like the Tegenaria domestica reaching sizes up to 1.5 cm in body length. Males are usually smaller than females.
• Coloration: Their coloration is often a mix of brown and grey shades, which provides effective camouflage against natural surroundings.
• Abdomen: Identified by their distinct elongated bodies and banded patterns on their abdomen.

Habitat: Tegenaria spiders are adaptable and can be located in diverse habitats, ranging from under stones and logs to the corners of buildings and basements particularly in urban areas. The Comunidad Valenciana's varied landscapes and climate provide an ideal setting for these spiders.

Behavior and Webs: As typical for funnel weavers, Tegenaria spiders construct horizontal sheet-like webs with a funnel retreat where they reside. This design is effective for trapping prey, such as insects, which the spider then quickly immobilizes with its venom.

Common Species: One of the commonly known species in the Comunidad Valenciana is the Tegenaria domestica, also referred to as the Common House Spider or araña doméstica in local terms.

Importance: Despite their sometimes daunting appearance, Tegenaria spiders play a crucial role in controlling insect populations, thus maintaining ecological balance. They are generally harmless to humans and tend to avoid contact.
