Opilio canestrinii (Thorell, 1876)
Opilio canestrinii is an invasive species which arrived in Nottinghamshire as recently as 2010, but is likely to have been present at least several years earlier. It is often found in gardens and on the walls of buildings and is certainly commonest in urban areas. In some parts of the UK, Opilio canestrinii seems to have replaced Opilio parietinus, but we have yet to record any evidence of this in Nottinghamshire and the two species can often be found sharing the same wall. Still less widespread than Opilio parietinus in Nottinghamshire and easily identified by the orange coxa and trochanter - the two leg joints nearest the body. The male is shown in the bottom two photographs.
