|Description: The anterior medial eyes are surrounded by black pigmentation. Carapace is yellow brown to dark brown with variable darker markings. Sternum is dark brown with yellow midline. Femora and tibia I thickened, femora and tibia II less so. The leg colour varies from yellow to dark brown, usually femora are dark brown apically, and the patella uniformly dark brown while remaining segments are lighter. The legs are spineless, except for one spine on femur I. Abdomen globose, higher than long, dorsal surface with silvery spots isolated by dark brown reticulations. Some silvery spots may have an orange tint. Midline area lacks spots in some places, however the exact pattern is very variable among individual spiders. Usually there are som transverse bars or wedges. Each side of the abdomen usually has dark areas lacking silvery spots. Males are less globose than females and the dark areas of the abdomen are sometimes larger than in the female and the light spots are less silvery. Palps of adult males are quite large compared to the body size. The species constructs small, modified orb webs, of which 2-5 radii converge before gathering at the centre of the web. A single thread is attached to nearby vegetation, and is held by the spider staying in the centre of the web. The thread is drawn tight such as the web is pulled into a conical shape. When prey encounters the web, the thread is slackened to enhance entangling. The females construct small spherical egg sacs with a brownish papery surface. The sacks are attached to the vegetation by long whitish stalks, usually higher up than the web. The egg sacks are very characteristic, and reveal the presence of Theridiosoma even if no specimens are found. Spiders of the Mimetidae construct egg sacks not unlike those of Theridiosoma, however they differ by having a woolly surface. Size: Female 2-3 mm; male 1.5-2 mm. Maturity: Males from May until June, females also until September. Habitat: Wet,more or less permanently flooded places with dense vegetation in wetlands, including lakeshores. The webs are built close to the water surface, usually under dark condtions such as under overhanging vegetation.
