This category contains lists of spider species, one for each family. If a family is not listed here, check for the family page at Araneae families . The species are mostly taken from various versions of the World Spider Catalog .
Now, however, it appears that non-orb spiders are a subgroup that evolved from orb-web spiders, and non-orb spiders have over 40% more species and are four times as abundant as orb-web spiders. Their greater success may be because sphecid wasps , which are often the dominant predators of spiders, much prefer to attack spiders that have flat webs.
Paintings of Araneus angulatus from Svenska Spindlar of 1757, the first major work on spider taxonomy. Spider taxonomy is the part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida, which has more than 48,500 described species.

The Agelenidae are a large family of spiders in the suborder Araneomorphae.Well-known examples include the common "grass spiders" of the genus Agelenopsis.Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (Eratigena agrestis) may be medically significant, and some evidence suggests it might cause necrotic lesions, [1] but the matter remains subject to debate.

Spiders, unlike insects, have only two main body parts instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). The exception to this rule are the assassin spiders in the family Archaeidae, whose cephalothorax is divided into two parts by an elongated "neck". In the majority of ...
Joro spiders from East Asia are weaving their way into the U.S. landscape. Understand their habits, habitats, and how they affect local ecosystems.
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", [ 1 ] hence the English name of the group.
Gasteracantha has a complex taxonomic history, and many questions of species limits and distribution and generic interrelationships remain unanswered. Furthermore, challenges include the variability within individual Gasteracantha species (e.g., color polymorphism and variable length and shape of spines), a lack of male specimens and descriptions for many species, missing or damaged type ...
