5 Interesting Facts About Black and Yellow Garden Spiders

Black and Yellow Garden Spider

Here is a black and yellow garden spider showing off its cool zigzag patterned web

Today I want to write about a really amazing spider that has a cool web, the black and yellow garden spider.

Here are five interesting facts about them:

  1. Also known as black and yellow argiopes, these lovely little spiders grow up to 3 cm long, with the females twice as large as the males.
  2. They are a kind of orb web spider and they build large round webs up to two feet across.
  3. They make a clear zigzag pattern of silk in the middle of their web and wait there for their prey to fly into it.  They are most active during the day and catch and eat flies, grasshoppers, crickets, wasps, moths and bees.  Females can catch prey twice as big as they are.
  4. After mating, the males die and are often eaten by the female.  She lays large egg sacs in the web and guards them from predators until she dies when the weather starts to get cold in winter.  In spring, thousands of little spiderlings hatch and float away on the wind on strands of silk.
  5. Black and yellow garden spiders are very common and can be found in gardens throughout the United States and Canada.

I hope that you found these facts interesting and learned something new.

Are there any other interesting facts that you would like to share about black and yellow garden spiders?

  1. We had two beautiful black and yellow garden spiders take up residence outside a bedroom window. I check on them each day. One day I went out to find that one of the spiders was missing. Upon closer observation, I saw that the one spider that was missing was wrapped up nicely in the other spider’s web. I assume the unfortunate one was the male and the still living one is the female. A few days ago, I noticed, on the brick wall, a white web covering and whatever was inside was moving, I didn’t think it was the egg sac, but I left it alone. Then, today, I noticed an egg sack in her web. My question is, what is the web on the brick? Is it possibly something she captured and is saving, is it something else that may be waiting on her to die and prey on our babies, or what? I want to protect the babies.

  2. I live in OK. and they are abundant. An interesting fact I think, if you approach them and scare them, they will start shaking their web back and forth, as to intimidate.

  3. I have watched one all summer that has a web on the side of my shed. She now has four egg sacks at the top of the web. I like them.

  4. I have a black and yellow garden spider and check on her everyday. I haven’t seen her since last night and am worried about her. She did not rebuild her web overnight. There is at least one egg sac I can see. It’s still warm here so no frost to kill her. Could she have just left? Is it possible something ate her? I have a male in another shrub and he’s fine.

  5. I was mowing my acreage today, and came across at least a dozen of these !! I was wondering if this is an omen for the coming winter ???
