Tigrosa aspersa
This record describes Tigrosa aspersa (species). Recorded family: Lycosidae. Recorded order: Araneae.
Identification and Appearance
According to How to Know the Spiders , this species has a thin line of yellow hairs in the eye area and a more spotted venter than carolinensis. It also has banded legs. According to Penn State Entomology, here's a description: Hogna(Tigrosa) aspersa females are 18 to 25 millimeters in length, and the males are 16 to 18 millimeters. They are similar to H. carolinensis in body color but have a distinct narrow line of yellow hairs on the carapace in the vicinity of the eyes.

About Spiders: the wider group
Order-level background for Araneae, the group containing Tigrosa aspersa. 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.
