(235ORvil) Orchesella villosa (Geoffroy, 1764)

*pilosa Lubbock, 1862
*terrestris Brown, 1929

Orchesella villosa is widespread and common in southern England and Wales, but appears to become increasingly scarce as one moves further north (Arne Fjellberg has not recorded this species from Fennoscandinavia). It is one of our largest species reaching 5.0 mm in length. The pigmentation on the body is quite variable (Figs. 1 to 5) and it is possible that there may be more than one species 'hiding' under the name 'villosa'.  Any specimens referrable to this species found below the high tide mark may be O. littoralis (recorded only once by Bagnall, 1925, from Runswick Bay, Yorkshire).  Although distinctively marked, O. quinquefasciata may just be a colour variation of this species.


The basal segments of the antennae are usually dark. However, the 'hairs' are often rubbed off.
