Taxonomy
Order:
ARANEAE
Family:
AGELENIDAE
Species Comment:
The 5 Agelenopsis species reported from NC "resemble each other closely in general appearance. Even in the same species there is much variation in size and some in depth of color. Our [five] known species can only be distinguished with certainty only by a comparison of the genitalia." (Kaston, 1948)
Identification
Online Description/Photos:
Agelenid species can be differentiated from other sheet web-making families by the following: Amaurobiidae and the NC Dictynidae are cribellate, which Agelenidae are not. They can also be differentiated by some other families (Cybaeidae, Hahniidae, and Miturgidae) by their particular spinneret sizes and arrangements.

Total Length:
The 5 species known to occur in NC range in size from 8-11mm (emertoni) to 16-20mm (naevia) for the females and 8-9mm (Kastoni) to 13-17mm (naevia) for the males
Adult ID:
identifiable by photo of specific features and/or supplementary info
Structural Features:
The family Agelenidae resembles wolf spiders (Lycosidae), but has a different eye pattern, and notably long spinnerets; furthermore, agelenid spiders form sheet capture webs, while the Lycosidae make no such web, being active hunters. A comparison of the genitalia of the 5

Habitats and Life History
Habitats:
Observation Methods:
Abundance/Frequency:
Silk / Web:
Usually a non-sticky, horizontal sheet with a tubular retreat.
Behavior:
The spiders are very sensitive to vibrations on their non-sticky webs, and rush out from their tubular retreats to seize prey. Those retreats are open on both ends, and they readily use the "rear exit" to avoid predators.
