I discovered this tiny spider in my study room. I popped him in a container to snap him before releasing him outside.
The abdomen of this sac spider is reddish-brown with a darker cardiac mark, and has a velvety appearance. Body length up to 9mm.
It is a nocturnal hunter of invertebrates.
The adults are seen spring to autumn. Found in various habitats amongst low vegetation and leaf litter. Common and widespread throughout Britain.
Photograph taken May 2014, found in house, Staffordshire. Camera used Nikon D3200, with Sigma 105mm macro lens.
