Excellent laminated multi page double sided Field Guides from the Field Studies Council.
This 12-panel laminated fold-out chart covers the adults of the harvestmen found in the field in the British Isles. Harvestmen are spider-like invertebrates that are most commonly seen in late summer and autumn. Although they have 8 legs, the whole body is fused into one unit, without the ‘waist’ seen in spiders.
With photographs of each species on one side, and text information on the other, it will allow you to make a positive identification quickly.
