Spotted Orb Weaver (Neoscona crucifera)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Spotted Orb Weaver.

 Updated: 8/29/2017; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




Covered in short hairs, the Spotted Orb Weaver is a commonly sighted arachnid that is both hunter and hunted.



Spotted Orb Weavers spin orb-shaped webs that are up to 2 feet in diameter. During the day, they usually hide in a curled leaf near the edge of their web. Individuals can vary in color: some appear more orange/red while others are more yellowish-brown. The markings on their abdomen can also vary between individuals in this species. Some have a pronounced 'cross' on their abdomen; others have darker zigzag stripes down by the end of the abdomen. All of them have the bristles on their abdomen, legs, head and thorax.

Spotted Orb Weavers can be found in woodlands, chaparral, fields, gardens, parks and backyards. They are active mostly between May and August. These hairy spiders are nocturnal, but it isn't unusual to see one during the day.

Females lay eggs in a sac spun from their silk. It hangs near the web until the spiderlings hatch. Although spiders are usually the hunter, the spiderlings of this species are frequent targets for mud dauber wasps.

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).
