theridiid

Theridiid is a family of spiders belonging to the order Araneae. They are characterized by their distinctive body shape, with a long, slender abdomen and a relatively short cephalothorax. Theridiids are known for their intricate webs, which are often constructed in leaf litter or other sheltered locations. These webs are typically radial, with a central hub and radiating spokes, and are designed to capture prey by ensnaring it in sticky silk.

Theridiids are found worldwide, with over 1,000 species described. They are particularly common in tropical and subtropical regions. The family is diverse, with members ranging from small, inconspicuous spiders to larger, more robust species. Some theridiids are known for their venom, which can be harmful to humans, although most species are not considered dangerous.

The scientific name Theridiidae is derived from the Greek word "theridion," meaning "web." This reflects the family's distinctive web-building behavior. Theridiids are an important component of many ecosystems, contributing to the control of insect populations and the decomposition of organic matter. Despite their ecological significance, theridiids are often overlooked in spider research due to their relatively small size and cryptic behavior.
