Centromerita bicolor

This record describes Centromerita bicolor (species). Recorded family: Linyphiidae. Recorded order: Araneae.

Identification and Appearance

Centromerita bicolor - Centromerita bicolor
FeatureDescription
Additional detailsSize 3.0 to 3.5 mm.
CarapaceCarapace and legs unicolourous brown to dark brown. Male head with a number of forward directed spines, fewer in females.
AbdomenAbdomen brown to dark brown. If brown then the abdomen has the same colour as the carapace and legs. If dark brown then the abdomen is darker than the carapace and legs. Identification of this species requires microscopic examination of the genitalia of mature specimens. Occurs in a wide range of habitats, including grasslands, heathland, bog, hedgerows, wasteland and allotments, but perhaps especially in improved and disturbed grasslands and other places with areas of open ground. http://srs.britishspiders.org.uk/portal.php/p/Summary/s/Centromerita+bicolor http://srs.britishspiders.org.uk/resource/Identification-Centromerita-bicolor-concinna.pdf No additional images available for this species.

About Spiders: the wider group

Order-level background for Araneae, the group containing Centromerita bicolor. Species-specific details appear above.

Group overview

As of 2023, 51,673 spider species in 136 families have been recorded, though an estimated 150,000 species exist. Spiders rank 7th in total species diversity among all organism orders. Only 0.5% of spider species pose any risk to human health.

Ecological role of the group

Spider venom contains complex peptides with diverse pharmacological activities, making them valuable for drug development research. Spiders produce up to 7 types of silk from specialized glands. Spider silk genes have been inserted into mammals and plants for biotech applications.

Economic and practical significance of the group

The global spider community kills an estimated 400-800 million tons of prey annually (2017 study). Spiders provide billions of dollars in natural pest control for agriculture. Spider silk is 5× stronger than steel of the same diameter, driving a biomaterials research industry.

Recorded sources for this group: World Spider Catalog, PNAS, Nature, ScienceDirect. Imported estimates may describe particular regions or reporting periods.
