Tube Web Spider - Segestria senoculata

    Family - Segestriidae
    Genus - Segestria
    These Spiders live in Tubular retreats - holes in walls and bark
    and sometimes under stones. The retreats have trip wires connected to
    the entrance. I have observed them backing up and seemingly,
    pulling 'curtains' shut inside their tubular retreat
They are quite aggressive Spiders and are very fast. They rush out to grab
    prey then drag it back into the retreat. First three pairs of legs point forwards.
These Spiders are also known as Snake - Back Spiders.
They have six eyes. Cylindrical, elongated Abdomen.

    I observed this False Widow - Steatoda nobilis,
    assuming she had been bitten by the largest Segestria senoculata living
    in my back garden walls.
    It took her two days to die. She twitched and shook throughout.

Unidentified Spiders

These are Spiders that I have not been able to identify or cannot be sure
of by using the Collins Guide,

or am unsure of. Any help will be greatly appreciated.

Unusual Crab Spider
    Thomisidae
Ozyptila sp. perhaps?
    Brighton, East Sussex
    25.08.11

    My friend Janet Henbane sent me this Photograph of a rather large
    looking Spider that she found in an imported box of Vegetables.
    I sent the image to Peter Harvey of the British Arachnological Society.
    "... may be a large lycosid Lycosa (L. fabrilis is our only British species,
    but it would not be this) or possible a Zoropsis. Either would probably
    originate from southern Europe".
