Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Araneae
Suborder Araneomorphae
Family Liocranidae
Genera
Agroeca
Neoanagraphis

Liocranid sac spiders consist of about 170 species of wandering spiders in 30 or so genera. The best known are those in the Holarctic genus Agroeca. Various genera of rather obscure spiders are included in the family, which still lacks a diagnosis. Two species in the North American genus Neoanagraphis are found in often hyperarid conditions in the Mojave, Sonoran and Chihuahuan Deserts. The females apparently live in animal burrows and the males wander and are often caught in pitfall traps.

Spider (2391 words)
Spiders reproduce by eggs laid in silk bundles called egg sacs, and the male (usually significantly smaller than the female) is likely to be killed by the female after the coupling, or sometimes before intercourse has occurred.
When sexually mature, a male spider will spin a web pad onto which the contents of the abdominal reproductive organs are discharged and then the seminal fluid is transferred into the cavities of the palpi; when an individual secures a mate he thrusts the palpi one at a time into her abdominal genital openings.
The widow spiders, brown recluse spiders, hobo spiders, and yellow sac spiders are the dangerous ones among U.S. spiders.
