LegsLegs have white rings. Female found in Florida: Introduced from Asia, recently.

Additional species information

Species notes from the sources

Etymology: Smeringopus means "hairyfoot" (from the Greek nouns), but there is nothing in Simon's description of the genus which seems to warrant this name, nor is there anything in Vinson's original description of the type species Pholcus elongatus Vinson 1863.

About Spiders: the wider group

Order-level background for Araneae, the group containing Smeringopus pallidus. 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.
