Turret Spider (Atypoides riversi)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Turret Spider.

 Updated: 2/8/2014; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




Turret Spiders are snatch-and-grab predators and their oblivious prey never see it coming.



Native to Northern California, the Turret Spider is part of the larger family of "Folding Trapdoor Spiders" that live in self-made burrows dug into the ground. Though other "Trapdoor Spider" types exist, Folding Trapdoor Spiders actually make use of a door or entrance made of plant debris for the burrow, making surprise attacks even more effective. Turret Spiders, however, do not construct doorways to their burrows and may choose to leave their burrows open all day long.

Identifying colors of Turret Spiders vary depending on the part of the body; have green and brown hues while others are more purple and brown. The legs sometimes look like a darker brown. Males are discernibly different in that their abdomen might feature up to 3 plate-looking coverings whereas the female has been seen with just a single plate covering the abdomen. Females are generally larger than males.

Turret Spiders are found outdoors and mostly limited to wooded areas that include pine tree forests, though some make their homes near the banks of moving water sources like creeks or streams. Favored dietary intake would be ants though just about any smaller insect will make a fine meal.

Turret Spiders like to forage for food in the nighttime hours and will take to wandering the grounds after generally substantial rainfalls. Some have been captured and sold as 'pets', though they are best observed in their natural environment.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.




Spider Anatomy
Graphic showing basic parts of spider anatomy
1
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
2
Pedipalps: Small appendages near the mouth used as taste and smell organs.
3
Cephalothorax: Contains eyes, head, mouthparts, and legs.
4
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
5
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).
