Leiobunum sp. A (Schönhofer & Hillen 2008, Toss 2009, Wijnhoven et al. 2007)
Leiobunum sp.A is a very dark, extremely long-legged Harvestman, obviously much larger than other Leiobunum Harvestmen in the UK, with a leg span of around 100mm. It first appeared in The Netherlands in 2004 and still remains scientifically unidentified to species level. It is believed to be a very invasive species, quickly forming large congregations numbering many hundreds on the shaded walls of buildings. We found the first ever record for the UK, on the wall of a house in Worksop in 2009. It was then found by Paul Richards on a factory wall in Barnsley in September 2012, just before we finally located this Harvestman again on the walls of Worksop Priory in October 2012. In 2018, it was recorded by Wil Heeney at a garden centre near Oxton, the first record away from Worksop and has since been found in a Nottingham suberb (Campbell, J.).
