Odiellus spinosus (Bosc, 1792)
This is a quite distinctive species, once some experience is gained with Harvestmen. ID is relatively easy with the trident (a cluster of spines in front of the eyes) consisting of three large, almost flat spines of near equal length. Most Harvestmen have a trident of unequal spine lengths than Odiellus spinosus and in this species, the abdomen is distinctly flattened in appearence. Odiellus spinosus is often found in gardens and around houses, and some websites show this species to have a southern distribution, but as this is a less studied group of invertebrates, accurate UK distribution is hard to determine.
