This past week, my daughter and I were out on the back porch planting the usual autumn perennials. It is always a special time when we do our “seasonal” planting together, we get to spend some quality time with one another and I have an opportunity to educate her on different species of flowers and plants, which is a tradition she will one day pass on to her daughter. We decided to plant huge yellow chrysanthemums in correlation with rust colored majestic pansies both of which are so lovely this time of year against the changing leaves within the landscape. As we were busy getting our hands dirty, my daughter pointed out a large spider web right off our back porch attached to the azaleas around it. The spider was in a circular shaped web and the spider residing there was quite large, and scary looking, but yet beautiful in its own way. I discouraged the thought of getting rid of the spider until I learned more about this mysterious beauty. I was curious about the type of spider we have living in such close proximity to our home and decided to do a little research on the spider.
My gut feeling was that the spider we found was a “writing” spider reminiscent of the mythical spider from my favorite childhood book by E.B. White, “Charlotte’s Web”. My intuition served me well. My findings concluded that the spider we have residing within our azaleas is actually an Argiope, or black and yellow garden spider, also known as a corn spider, and referred to as a writing spider as well, just like Charlotte from my beloved childhood novel.
What I discovered is that our guest, the black and yellow Argiope, is a common spider found among fields and gardens because they like to spin their orb shaped webs among bushes , tall plants and flowers. The female Argiope is a good bit larger than the male, and judging by the size of ours, she is obviously a female. The female spins a large web which spirals out from the center and can be as large as two feet across. The male spider will then spin a smaller web for himself on the outside of her web and is has a characteristic zig-zag pattern. We have not yet caught a glimpse of Mr. Argiope yet, but are hopeful to catch a candid soon. The interesting thing about the Argiope is that each evening the spiders will eat their web and build a new one.
The purpose of the web, like all spiders is to trap and digest prey such as insects which are the spider’s main food source. The web also serves as a nursery where the female will lay her eggs on one side of the web and cover them with a papery sac for protection until they hatch in the fall. Then the baby spiders will remain within the protective sac throughout the winter, and will leave when mother nature harkens the arrival of spring. A single egg sac can contain over one thousand eggs. The Argiope like almost all spiders is not harmless to humans and rarely, if ever bites humans except in the rare instance as a defense mechanism if they are grabbed.
There is more to this stunning spider than meets the eye, the black and yellow Argiope eats mosquitoes among the many insects that get caught in its web, which cuts down on the amount of disease carrying mosquitoes that are thriving along the realm of my backyard. Suddenly this spider is beginning to become my friend. They also dine on aphids and flies as well, this spider is helping cut down on mosquito populations and helping to keep aphids off my rose bushes? Based on these findings, we have decided to let the black and yellow beauty make herself at home. We will not disturb her as she raises her young and has her gourmet dinners of my aphids, flies and mosquitoes and other garden pests. Bon appetit !
So, before you squash that spider that makes you squeamish, give some thought to the many ways it may be of great benefit to you and the world around you. Many of the world’s most scream inducing insects and animals, like the spider and the bat, benefit us from being natural predators of potentially dangerous insects such as mosquitoes, making them an effective weapon is the battle for mosquito control. For every mosquito they dine upon is one less we have to potentially put us at risk.
