Steatoda nobilis

    Description

    Sometimes known as the Noble False Widow spider - adults of both sexes are usually larger than both Steatoda bipunctata and Steatoda grossa - the body length of an adult female false widow spider is around 15 millimetres, males are a little smaller. Maximum leg length of both sexes is about 25 millimetres. The abdomen is usually reddish and there is nearly always a distinct cream or whitish band around the front of the abdomen. Some paler markings are also present on most specimens.

    Identification difficulty
    Habitat

    Steatoda nobilis is strongly synanthropic and is most commonly found in and around domestic and commercial premises, including conservatories, public toilet blocks, garages and sheds.

    When to see it

    The males are mature in the summer and autumn, the females probably throughout the year.

    Life History

    The bite in most people would be little different to a bee sting, and there are currently few definite recorded occurrences in Britain since 1979. It constructs a scaffold web that differs from others of the genus in the exceptional strength of the silk and in the tubular retreat that is at least partly concealed in a deep crack or hole.

    UK Status

    The false widow spider commonly occurs along a stretch of the south coast of England from Devon through to Dorset, Sussex and more recently along to Essex. It is believed to be increasing its range further north.

    VC55 Status

    Rare in Leicestershire and Rutland – the Sapcote specimen of 11th July 2015 is only the second record of this species in VC55.

    Further Information

    There have been 503 British records for this species to 2015.
