Pholcus phalangioides
Very common & widespread throughout the British Isles.
Also known as Harvestmens & Celler Spiders.
The bodies of P. phalangioides, as with all spiders, can be divided into two parts: the prosoma and the opisthosoma.
The prosoma is commonly known as the cephalothorax, and the opisthosoma is commonly known as the abdomen.
Most of the prosoma is occupied by the brain.
The eyes are arranged such that there is a pair of smaller, dark eyes at the front of the prosoma followed by three parallel rows of pairs of larger eyes.
It takes about one year for these spiders to mature after they are born, and their life span is up to two years or more post-maturity.
