False widow spiders are distinctive for their shiny, black flesh, bulbous bodies, thick legs and skull-like patterns . False widow spiders are distinctive for their shiny, black flesh, bulbous bodies, thick legs and skull-like patterns. Millions of false widows, Britain's most venomous spider, have been found across the UK and the population is believed to be growing. The species has a brown bulbous abdomen with cream markings that look like a skull. They have long legs and can reach about 15mm in size. Also known as steatoda nobilis, the spider is frequently confused for the black widow, which has deadly venom. The false widow was first spotted in the UK in Torquay, Devon, in 1879, and it is understood that it may have made its way to these shores from Madeira or the Canary Islands in a shipment of bananas. The Natural History Museum says that warmer summers mean the spider is spreading northwards through the UK, having been found mainly in southern England.
