Ostearius melanopygius (O.P.-Cambridge, 1879)
A very small, yet distinctive spider. The dark grey/blackish carapace, coupled with a bright red abdomen, makes Ostearius melanopygius relatively easy to identify when examined under a hand lens and experienced recorders will soon recognise it immediately. A cosmopolitan spider, which is suspected of having arrived into the UK via importation from abroad. Widespread across most southern counties of the UK, there are several known Nottinghamshire records. This male and female (top photographs) were found underneath cut vegetation near Rufford in early October 2015.
