Wolf spider lycosidae trochosa terricola close up
Description
Male Trochosa terricola are 7–9 mm in length while females are 7–14 mm. Similar in appearance to other Trochosa species, the female T. terricola has a reddish abdomen while the male has darkened front legs. The two short lines which are visible on carapace are a diagnostic feature of Trochosa wolf spiders. The light cardiac mark separates it from Trochosa ruricola which has a dark cardiac mark.
Habitat
T. terricola is found in woodland, grassland, heathland and industrial sites and is often encountered under stones and logs, but overall it shows a preference for drier, heath-like conditions, although has been found in pitfall traps in areas of bog and marsh. Unlike the related T. ruricola it can be common in upland areas.
Biology
Adults, both males and females, have been recorded from March to November, with a peak from spring to mid-summer, although in warmer areas in can be active throughout the year. This spider generally appears more sluggish than the Pardosa wolf spiders with which it is sympatric. T. terricola is normally most active at night. It has been recorded as a prey item of the pompilid wasps Priocnemis perturbator and Anoplius viaticus
Distribution
Holarctic, in Europe it is found throughout the continent and Great Britain and Ireland but is absent from Iceland.
