Mouse Spider - Scotophaeus blackwalli
Approximately 9 to 12 mms long. The Mouse Spider gets its name from the grey coloured abdomen which is covered in tiny hairs and resembles mouse fur. 3 dorsal spines on femur III & IV.
Scotophaeus scutulatus (rare) - 2 dorsal spines (proximal and median, no distal spine) on femur III & IV.
A clear photo showing the spines on the upper surface of femur III &/or IV is required.
In southern Britain they are found in gardens and houses. In the north they are found mainly indoors.
