SPIDERS AND MITES
The Tegenaria Domestica measures between 8 mm and 12 mm, males between 6 mm and 9 mm. It has a brown body with darker patterns on its abdomen.
This spider feeds on live insects and other arthropods, as long as this is smaller than it. Sometimes it catches in its web.
Tegenaria Domestica is found indoors in dark corners. It occurs often in the most common parts such as the dining room or living room.
The queen and males mate in flight (swarming), usually in May. The queen's abdomen has a spermatheca, a small pocket, which contains sperm. This small receptacle produces nutrients that keep the seed alive for several years, so the queen can lay thousands of eggs without needing to mate again.
