Silver Garden Spider (Argiope argentata)


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

Silver Garden Spiders are a precious resource to have in a garden or park. They consume plant-harming insects and add a gleaming luster that few others can offer.



The Silver Garden Spider can be found in the warmer, southern parts of North America. Young spiders can survive a frost, but that hardiness diminishes with age. They reside in parks, gardens or other open areas that have plants.

The silver color on this helpful spider develops over time and this orb weaver can grow to be quite large in the garden. (Note: the size references for insects and arachnids do not include legs!)

They weave their webs between plants or cacti and have an X-shaped stabilimentum (a zigzag pattern of thicker silk in the web). The stabilimentum aids in identifying it as a part of the garden spider family. They can be found sitting head-down in the middle of their webs.

Few female spiderlings survive to maturity, but most of the males do, are they are usually eaten by a female after mating with her.

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).
