This record describes Pachygnatha listeri (species). Recorded family: Tetragnathidae. Recorded order: Araneae.
Identification and Appearance
Length 3 to 5mm. Prosoma reddish yellow, or brown with dark median band, margin not darkened. Sternum dark brown. Chelicerae dark brown. Legs yellow-orange. Opisthosoma grey, mostly with almost black folium dorsally, with bright pairs of spots along median line, folium in females sometimes only vague. Microscopic examination of genitalia is required to confirm this species.

About Spiders: the wider group
Order-level background for Araneae, the group containing Pachygnatha listeri. 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.
