Black and Yellow Garden Spider Egg Sac

(Argiope aurantia)

2 EGG SAC ONLY

Some species of spiders (including wolf and jumping spiders) overwinter as young adults and mate/lay eggs in the spring. Many spiders, however, mate in the fall, after which they lay eggs and die. Their white or tan egg sacs are a familiar sight at this time of year. One might assume that these species overwinter as eggs inside their silken sacs, but this is rarely the case as spider eggs can’t survive being frozen. Spider eggs laid in the fall hatch shortly thereafter and the young spiders spend the winter inside their egg sac.
Although egg sacs provide a degree of shelter (the interior is packed with very fine, very soft silken threads), the newly-hatched spiderlings do have to undergo a process of “cold hardening” in the fall in order to survive the winter. On nights that go down into the 40’s and high 30’s, these young spiders start producing antifreeze compounds, which lower the temperature at which they freeze. By the time freezing temperatures occur, the spiders are equipped to survive the winter inside their egg sac – as spiderlings, not eggs.

Argiope aurantia

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. 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.
