|Pachygnatha listeri have a broad, oval rear body (Opisthosoma) which in different variations is coloured. On the upper surface there is a pattern in the shape of a leaf (folium). The edges of the folium are usually strongly undulated, but on some specimens they appear only slightly sinuous. In the centre of the folium, which is often darker on the males than on the females), white spots are visible, often in pairs. The legs of the Pachygnatha listeri are reddish or brownish in colour, long, shiny and without spikes or markings. |
Pachygnatha listeri prefer wet and shady habitats, but can also cope with drier environments. . They can be found in the open air (in humid forests or bush land) as well as in buildings and mainly live on the soil under stones, leaves or moss.
|The adult spiders are encountered throughout the year and hunt small insects like springtails (Collembola), aphids (Aphidoidea), Diptera and others. They donít build webs. |
Pachygnatha listeri often appear in the company of Pachygnatha clercki and in the vicinity of Zygielle x-notata.
Mating may take several hours and is normally non-fatal for the males. For oviposition, the female produces a flat, white cocoon, which it fastens amongst moss, under a stone or under dry leaves. There is no brood care. The newly hatched spiders can be found just above the ground. They catch prey with small orb-webs that they build. In adulthood, they no longer use webs, but walkaround hunting insects.
