Predation on a pygmy shrew, Sorex minutus, by the noble false widow spider, Steatoda nobilis

Abstract The noble false widow spider Steatoda nobilis is a globally invasive species with implications for public health and possibly for native ecosystems. Here, we report on a case of predation on a protected species of vertebrate, a pygmy shrew Sorex minutus in Britain. The importance and novelt...

description Abstract The noble false widow spider Steatoda nobilis is a globally invasive species with implications for public health and possibly for native ecosystems. Here, we report on a case of predation on a protected species of vertebrate, a pygmy shrew Sorex minutus in Britain. The importance and novelty of this report are: (1) this is the third documented case of S. nobilis preying on a vertebrate in five years, suggesting that small vertebrates are likely to be a more frequent component of their diet than previously thought; (2) this is the first case of a Theridiidae spider preying on a shrew in Britain; and (3) this is the first case of predation on shrews by the genus Steatoda globally. Overall, S. nobilis fits the profile of a habitual vertebrate‐eating spider.
