The ubiquitous Black and Yellow Garden Spider is a steadfast sentinel, diligently guarding over our gardens.





Black and Yellow Garden Spiders are from the Argiope genus and are found throughout the United States of America and Canada. This species is not quite as common in the Rocky Mountain areas as they area everywhere else. The spider is easily identifiable by the distinctive yellow and black coloring found on the abdomen. The legs are equally noticeable by the alternating bands of orange-yellow and black, though this pattern may vary from spider to spider. Females are larger than males; almost four times bigger. Besides being smaller, males do not promote their colors as much, and may appear a shade or two paler compared to the saturated colors seen on the female.

Webs produced by the Black and Yellow Garden Spider are about knee-high off the ground in sunny, still areas of a garden. They are also distinct as some have a thick silk strand that zigzags down the center of the web. This is called the stabilimentum. Additionally, their webs are built in a spiral that builds out from the center; a classic feature of Orbweaver spiders. These spiders sit on the web up-side-down with their heads closer to the ground. Their long, lean legs make them appear substantially large and quite intimidating to humans, but they are not aggressive. If disturbed or threatened, this spider may immediately drop to the ground in an attempt to flee and hide. It may also begin bouncing on its web in an effort to confuse a predator by making it difficult to get a clear view of it. Watch this bouncing behavior in slow motion here:



Black and Yellow Garden Spiders are also called a Common Garden Spider, or a Yellow Garden Spider in various publications. Whichever name used, spotting one of these spiders is quite a treat as their unique shape and striking colors add a bit of natural drama to your garden. They are commonly found in backyard gardens, parks and woodlands. Adults are most visible during the day in the summer. Females lay eggs in a papery brown sac which is then attached to one side of her web. She dies before seeing her eggs hatch. The eggs hatch in the fall, but the spiderlings stay in the egg sac over winter and venture off on their own in the spring.

Spider Anatomy (Typical)
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).


Territorial Reach (A-to-Z)
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 below as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections below indicate that the subject in question has not been reported in that particular territory.

Territorial Area Map (Visual Reference Guide)
The map below showcases (in red) the states and territories of North America where the Black and Yellow Garden Spider may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. Some species are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America.
