|Pachygnatha listeri - Tetragnathidae|
|Adult females can reach body lengths of 3-5 mm, males, 3-4. 5mm. The sexes are similar in shape and are light brown, reddish-brown or dark brown in colour. The front part of the body (cephalothorax) is pale yellowish brown to reddish brown in colour and without markings. The weak dark side edges are often difficult to recognize. On the surface of the back are dark-brown stripes which widen in the direction of the eyes without touching them. The front eyes and rear side eyes are close together. Sometimes they even touch. The deep black fangs (chelicera) are compared with the enlarged eyes. Their poison claws are long and thin. |
|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.
