Species Opilio canestrinii (Thorell, 1876)

Body Length 8 mm.

A long-legged harvestmen where the female is larger than the male. The male is reddish-orange in ground colour, where as the female is lighter in comparison.

It rests during the day and hunts for small insects and other harvestmen at night. Seen July to November. Found in urban environments, in gardens and around houses, and on brownfield sites and in parks.

An invasive species which colonises areas very rapidly. It is becoming more widespread and common in Britain, and may potentially displace other species as it already has in other parts of Europe. It is believed to have colonised northwestern Europe from Italy and is quickly spreading throughout Great Britain. It was first seen in October 1999 beside a reservoir in the Lea Valley, Essex.
