The Jewelled Spider is also known by its Latin name - Gasteracantha Minax, meaning "threatening and projecting". They are also known as spiny orb weavers and are part of the orb weaving spider family. This spider's body is very broad and grows to the size of a 20c piece, with its 8 legs being the length of a pin (fairly short for a spider). Its abdomen is strikingly coloured with bright yellows, orange or reds as well as white and black. Six stout spines (long and sharp) come from the border of the abdomen.

Hi Glen,
I found this spider in central Alabama, after looking around your sight I'm guessing it's a member of the Micarathena family?

15 October, 2005:
Hi, I found this spider building a huge web on my pool screen, can you please tell me what it is? Thank you

I was camping with my dad a few years ago, and he almost ran into this spider. It has a mostly black body, with yellow spots. After hearing that, it would seem to be one of thousands that fit the description, but here's where it gets weird. It had a crab-like body, wider than it is long, and its shell had two spikes on the front and two on either side. The spider was approximately a quarter-inch wide. I've attached a picture of this strange spider. I hope you can tell me what it is. If you don't have a picture of this type of spider, I have a higher-quality, larger-sized version of the picture you can use for your website. Thank you.

Hey Glen, Just wanted to say thanks to this site for helping me identify this Jewelled Spider that has been living in our backyard for a while. I live in Austin, Texas and this is the second time I've seen this amazing creature. Attatched are some pictures of the little guy, as well as one picture of a female that I took a while back. I'm an aspiring photographer and it really has been a pleasure to shoot these! Since seeing the female so long ago I was so incredibly fascinated by it's web and features- I wanted to take it in so I did for about a week. It certainly is an interesting spider. Thanks again for just a very great, informative site.
Kind regards,

I have a nice picture of a perhaps Jewel Spider. Could you confirm that? Thanks.

 I found your site several months ago to show my boys some neat looking spiders and info. Well...now I have my own picture to send and ask....what the heck is it? I sent a top view and the underside. It is very small, about 7x10mm with bright red horns. Kinda looks like a crab. I am in Florida...Clearwater area. When you get the chance I would love to know some info on this interesting little creature.

hi i was in my backyard and stumbled across this spider and thought it was the coolest and thanks to your site i figured out what it was. port saint lucie, fl

30 December, 2004:
Glen, I saw this amazing looking spider outside of my home and had no clue what kind it was but found out on your site from a google search. I have attatched 3 pictures of it. Let me know if you post it to your site.  Thank you for all the information you provided. The spider was found at my home in Houston, TX Charles Tips

First off, love the site! Well attached, please find two pictures of a Jewelled spider I found my yard in Houston, Texas. Kinda spooky looking. Also, the second picture shows her from the side as she was walking on her web. Can you please tell me if these are poisonous? Thanks, David Gian

My husband found this spider in a tree in our backyard in Louisiana. Thought the pics might be good on your site. can you tell us if this spider is harmful to us or our dog? Thank You, Shaunna Martin, New Orleans, LA

Hello, I live in Ft.Lauderdale, FL. these pictures were taken outside my living room window a day after hurricane frances passed us by. I watched this brave little spider endure high winds and heavy rain. I got attached to her during these times, I figured as long as she's still hanging there, me and my family would be too.

I found your site, which helped me identify this guy as a "Jewelled Spider". He's living on my apartment balcony here in Houston, Texas, and I first noticed him not long after I moved in at the end of May. He's definitely the coolest looking spider I've ever seen!

13 August, 2004
I found this Spider in the Northern Hills of Thailand. I have asked a friend who is a keen collector who couldn't identify it. I was wondering if you could help?

Howdy from Austin Texas. Love your website! I noticed that you called
this critter a "jewelled spider". Here in Texas, where these spiders  live in great profusion, we call'em spinybacked orbweavers  (Gastercantha cancriformis). They come in yellow and red, too. This one
has been living in my deck umbrella since April. It looks pretty wild,
but it's only about 1/2" long.

I found this spider after a trip into the rain forest near Tully, Northern Australia. Can you help me identify him

Found this one on a broken branch with ball moss. Was weaving a web to a potted plant about 2-3 feet away.

See attached! Have a few more if you need 'em. This shot is clear, so you can zoom in a lot.

Could you please help us to identify this spider see attachment

Thank you very much

Like Mr. Falkstein we found (and released) Gasteracanthae in our back yard! We were excited to locate you website and identify them. The red one (which we have not seen in any other spider sites) was about half the size of the white one. They were both found in a white ash tree about two feet apart. The white one had a well developed horizontal (like a hammock) web with occasional narrow patches of dense white web about one by one-eighth inch long every three inches or so. They both liked to hang upside down at one end of the web. When releasing the red one, it “played dead” for several minutes before crawling away. The Marte family, Cypress, Texas

Attached are pictures of a beautiful spider I found in my back yard. It seems to be a female "Gasteracantha cancriformis" (or Hasselt's Spiny Spider Gasteracantha hasseltii).
In all my years in Austin, Texas, I have never before seen a spider like this one.

Reply: The photos provided by Frank Falkstein (July 12, 2003 (photos show 07/10/2003)), Rich Elsner (October 28, 2002 and 11/6/2001), Jean Taylor (May 2, 2002), Lisa McAnelly (no date provided) are female "Gasteracantha cancriformis" (spinybacked orbweaver). The name, "Gasteracantha elipsoides" (Walckenaer) 1841 is a synonym for the formal name, "Gasteracantha cancriformis" (Linnaeus) 1767." The color of the female's dorsum varies by location. In Florida, the females are usually white with black spots and red spines. In other areas of the US where they can be found, the coloring of the females may vary and includes a yellow dorsum with black spots and black spines.

"Gasteracantha hasseltii" is a similar species that is found in Southeast Asia.

Good afternoon Glenda,
Of all your photos (including mine) of the Gasteracantha Elipsoides, none have a good shot of the underside. While walking the woodlands today I found this fine spider with her flip-side towards the sun.  Keep up the great work and the great web site. You are doing a great service for our little eight legged friends. Rich Elsner,

Interesting site. I'm looking for someone to identify a very interesting and beautiful spider in my yard. I have a good picture of it that I could email to someone. My
husband calls it a "Crab Spider". It does look lik a crab. I'd like to know more about it.
Jean Taylor
Dear Glenda,
This is the spider crab that was in our yard. I hope he returns soon. I haven't seen "him" for a few days, nor a smaller one like him either. This one is about 1/4" across.
Jean Taylor


Good evening Glenda, I'm pleased to see my Orb Weaver spider (the one with the purple star on his back) on your great web site. This morning one of my Florida neighbors called to say that he had an unusual spider on his pool cage screen. I collected the little guy and he now resides in my pool enclosure. He's doing really well and has constructed a new web about 24 by 24 inches.
I'm attaching a macro photo that I made while he was still on the screen. Use the photo if you like. Thanks for the great site and wonderful photographs.

Here's an answer for Arya:
Dear Glen
I visited your web site. It was quite informative. The photograph sent by Arya A. Sadhana Journalist, the Otosport Weekly, is Gasterocantha geminata, Gasterocanthinae
Dr. M. Ganesh Kumar, Thanks a lot Dr. Kumar
31/05/01 - Dear Glen,
I found your website by generating a search thru a search engine. Amongst all websites about sipders, I think yours is more informative and interactive one. That's why I write you an email. I'm a motor sport journalist in Indonesia. Last week, as I was covering an adventure off-road event thru the Gunung Halimun National Park, I spotted a strange looking little fella. Her web was hanging from a bush to a road sign this road sign was placed to alert the off-roaders from falling off the cliff right underneath the web). About 1 meter above the ground. Since that road sign was place a day before, the web is still fresh.
I wasn't so sure that she was a spider at first. But when I had a closer look thru my camera lens, I'm pretty sure that she was one. What attracted me the most was her extraordinary body shape. I thought it was an insect got caught in the web. Although I have a great concern about wildlife, I have never seen any spiders like this before. The temperature on spot where she was found was between 27 - 32 degree Celsius, in the heart of the National Park. It was pretty damp and humid, since Gunung Halimun (Mount Halimun) is eternally covered with fog (Halimun, in Sundanese language means fog). This little baby moves very fast. And by the time I wanted to took another pic of her, she already disappear. Please find them pictures attached. I'm also sending you several pics of her in separated emails so you can open it up easily. Unfortunately I didn't have my macro lenses with me, so I couldn't get a closer result. Not to mention that the pic of her underneath is kinda shaky (it's pretty hard to kneel down under a spider web - using a normal 28 mm lens - only about few inches before a 15 metres cliff). I'm wondering if you, or anybody can help me identify this little poor baby. I'm afraid that she's might be an endangered species. Please inform me via email, since I travel a lot and don't really have the time to check out
websites. I appreciate your great help and attention. Looking forward to hearing from you soon. All the Best, Arya A. Sadhana, Journalist, the Otosport Weekly
Could be a jewelled spider, any ideas on this one?
