Harvestmen
P.R.Harvey
Like the spiders of the Forest, the harvestmen have not been comprehensively worked. The Rev. O.
Pickard-Cambridge recorded 3 widespread species in 1882 and F. O. Pickard-Cambridge recorded a
further 3 species in 1900.
The number of British species is small, only 23 or 24 * species, 14 of which have now been recorded
in the Forest. Most of these are probably widely distributed in the Forest. Species such as Oligolophus
tridens. Paroligolophus agrestis, Lacinius ephippiatus, Lophopilio palpinalis and Rilaena
triangularis are certainly numerous in some localities. I have also found the tiny delicate species
Mitostoma chrysomelas to be numerous at Sunshine Plain but with a very short adult season.
Opilio parietinus is highly synanthropic (Hillyaid and Sankey, 1989) and has been recorded on
walls in the Forest. The smaller Opilio saxatilis, once thought to be the young of O. parietinus, occurs
in relatively dry habitats such as heaths, grasslands and sand dunes (Hillyard and Sankey, 1989). The
species was recorded in 1900 by F. O. Pickard-Cambridge and I have recorded the species from
Sunshine Plain.
One of the most interesting species to be recorded in the Forest is probably Paroligolophus meadii.
The species occurs in the ground layer of relatively dry habitats such as chalk downs, heaths and sand
dunes (Hillyard and Sankey, 1989). In Essex it is a rare species with all recent records being from old
grassland or grass-heath habitats. It is adult through the autumn, winter and early spring period and I
recently found it to be quite common on Leyton Flats in late autumn.
* This depends on whether Mitopus morio var. ericaceus is considered a separate species or a variety.
Two new species have also recently been recorded from the south-west of England and are not included
in this total.
