The number of emails we've had
from people in the United States trying to identify the
Black and Yellow Argiope or
St Andrew's Cross spider (as we call our
Australian variety) is quite astounding!! I've had a lot of questions about where the Argiopes are going to, as
some people have noticed that theirs has disappeared. Unfortunately this
lovely spider only has a short life span and once she has produced one
or more
(usually no more than 3) brown, papery egg sacs, she will die. The egg
sacs are roughly round in shape and up to 25 mm in diameter; each
contains 300 to 1400 eggs. She attaches her egg sacs to one side of her
web, close to her resting position at the centre. Each female will watch
over her eggs as long as she can, but will die in the first hard frost,
if not before. The eggs hatch in Autumn ( fall), but spiderlings stay in
the sac during winter and emerge in spring. (Milne and Milne 1980,Heiber
1992, Faulkner 1999). The St Andrew's Cross Spider
doesn't have dangerous venom. Its bite causes a mild local pain.
There are also other varieties of Argiopes - The
Banded Argiope and Silver
Argiope being two that have been sent in frequently. There are links
to photos of these and other argiopes below as well. |

Feel free to post this picture on your site if you'd like. I very much appreciate the information and pictures on your site which helped me to quickly identify the spider. Found in my tomato garden as you can see.

Hi again
I'm sending my most recent pictures of "Spidey" (feel free to use) securing her 4th egg sac on Oct. 6th. The other picture is her yesterday. She is eating a lot and getting big. (again) Is it possible she may be getting ready to produce a 5th egg sac? How often does that happen?
Thanks again,
Kaye Ely |

Hello, I am trying to find out what kind of
spider / web I ran into. It was outside at night and the
spider was brown and good size. It had a black abdomen
with 3 yellow dots down each side of it. I took a
picture and it got agressive when I tried to turn it.
Thanks, Cliff |

Hello! Is this a Black and Yellow Argiope? I look like the ones featured on your site. I live in southern california and I've never, ever, seen a spider like that here before! |

"Spidey" has been with us all summer. She has 3 egg sacs and looks like she could lay another one. I'm very sad over the thoughts she won't be with us much longer. The nights are getting colder. I'm sure this is a silly question, but is there any way to bring her indoors? I wouldn't mind giving her a corner of my room and I'm sure the other house spiders wouldn't mind. Feel free to use my pic.
Thank you,
Kaye
p.s. love your website |

Hi Glen! I love your website Spiderzrule! It has helped me identify lots of spiders and I feel a lot more comfortable around them now. Here is a picture of a big Black & Yellow Argiope at my home near Denver Colorado. She likes to show off her belly. I don’t see any egg sacs yet so I’m guessing she’ll be doing that soon. She’s really fat. I guess they look scarier than they really are. Please share on your site if you’d like to. Jen |

Reply: They only live during the warmer months
and die off after laying their egg sacs when Winter
comes, so there's not a lot you can do to extend their
life span, sorry - glen

Hi,
I’ve been watching this spider in my Cana Lillies for weeks and now she has disappeared. Could the cold kill her? It’s been getting down in the 50’s at night.
thanks

Hello, my name is Jeremy and I live in Kentucky, USA. Yesterday, September 22, 2010, I and my mother came across these three spiders and did not know what they were or if they was venomous. If you could, please do the best you can to identify these spiders for us and let us know. It would be greatly appreciated.
Thank You,
Jeremy |

Hi there!
I was hoping you can help me identify this spider? My husband found it on our porch by the porch light. It was quite colorful and very pretty. And had spun a beautiful web. My camera is High definition So I will include photos 2 of the spider. We live in south central Oklahoma.... We would appreciate any help.
Dana
Thanks Glen! Here’s a couple of better pictures if you’d like to use them on your website. Even though I’m not a spider enthusiast, I have to admit it’s a beauty!
Thanks!

Dear Glen,
I have no need of identification of our magnificent "house guest", as I have already done the research. However, our 8 yr old daughter and I have come across your website in all it's "magnificent delicacy" and thought you may enjoy sharing some of our pics. She made her home in the outside of our dining room window earlier this month and we've enjoyed documenting her actions everyday and watching her produce her egg sac. Our daughter is going to use "Charlotte 2" as a 4H presentation project. We have many pictures, so here are just a few.
Sincerely,
Megan and Jessie, Mt. Jackson, VA

Hello Glen,
Spider found indoors. First photo. Seems a bit small, transparent, and indoors to be a Wolf Spider. I know what the outdoor Wolf Spiders look like.
I'm in South Texas just south of San Antonio, in Bexar Co. Very sandy here. Plenty of spiders and other arthropods/insects. Can you use the other photos?
Thanks,

Both of these spiders were found outside our house in Manchaca, TX.. The first one looks like he has a star on him. The second one is very unusual I think. If you could help identify them I would appreciate it. We look on your site
quite a bit around here. Thanks for having such a great website :)

Glen,
My husband took this shot of the Black and Yellow Argiope in N.E Georgia about a month ago. I had never seen anything like it before and found your website that immediately helped me identify it. I was so excited to find one in my own backyard today in NC; also relieved that it is harmless.
Thanks,
I love your website. |

The spider caught a moth in it's web, the kids thought it was cool but I told them to leave it alone.

Hi Glen,
Attached are 2 pictures of a spider that made a funny looking web on a palm tree. It was taken in Prairieville, Louisiana.
My step son said that he thought it was a banana tree spider but it doesn’t look like any pictures that I have seen of one.
Can you tell what it is? I know the pictures aren’t the best.
Always a Bon Voyage!

Hello,
Pleae help.
I have lots of these [see picture attached] in my yard (Jacksonville, Fl.)
I've never seen it catch anything but they must as they all are between 3 and 5 inches across. I've never been bothered by this spiders and I notice when the wind is very still they move/pulse their web to simulate windy conditions.
What is it? What is the name... should I keep them in the yard or exterminate?

Hi Glen,
Thought you might like to see another closeup of an argiope. It's the standard yellow and black one. This one was probably over 3" across the legs and is one of the largest I've seen. You're welcome to post it on your website if you'd like.
Thanks,

Hello Glen,
Love your site. It has helped in ID'ing some of the spiders I've photographed.
I'm attaching
- An argiope having lunch.
- A black widow
- Maybe a wolf spider. It was really enormous. It was larger than a sparrow. It would have been good to have positioned a ruler or something near the beast, but I wasn't going to get that close to it.
- An unknown spider
Cheers,
George,

Hi,
Can you help me identify this spider. It appears from what I can see to be most like a fisherman spider but I'm not sure.
For reference, I'm located in the Florida panhandle, about 1200 feet from water, though have a pool.
the spider was in bright sunlight on the pool enclosure.
Thanks

Let me first tell you that I have always said that I hate spiders.... however, I cannot help taking pictures of the ones I find interesting. THIS one was super fun to look at, and I love the palm tree looking shape in the web!!
So maybe, after thinking about it, I don't so much hate spiders...
Thanks!
