Golden Orbweaver

black and yellow spider
Location: Harrisburg, Pennsylvania
August 10, 2011 1:25 pm
My husband and I live in Harrisburg Pennsylvania. We found this spider in a pot of plants on our back deck. I think she’s beautiful and have left her alone except to take some pictures. I was content with her presence and still am, but today I went to look at her and noticed that she had molted!! She is now double the size she was before. I had no idea spiders molted and now I’m even more curious about her. Could you identify her for me?

Dear K. Ryder,
The best way to identify a creature is by its scientific name because that cuts across all language barriers.  This lovely spider is
Argiope aurantia, and it has numerous common names in English, including Golden Orbweaver, Black and Yellow Orbweaver, and Writing Spider, a name that refers to the zigzag stabilimentum that the spider weaves into its web.  Your individual is a female.  Males are much smaller.  You can see this recent posting for a photo of the diminutive male.  All creatures with exoskeletons, including insects, spiders, scorpions and centipedes, shed their skin and molt to increase their size.  The Golden Orbweaver is not an aggressive species, and the bite is not considered dangerous, however, we imagine if a large female decided to bite a person, it would hurt and be followed by some local swelling.

I didn’t really need an ID. I just wanted to know how the website worked as far as uploading photos. I don’t see the 2 photos I uploaded and was just wondering how it worked.
I guess the answer is that you get so many submissions that you can’t get to all of them! LoL
Thanks anyway!

Hi Kathy,
Your spider is definitely one of the Orchard Spiders in the genus
Leucauge, and we believe it is Leucauge venusta even though there is more magenta in the spider’s body than we generally see.  We closely monitor the content on our site and our editorial staff posts all selected identification requests.  We do not allow contributors to post directly, except in the comment section, but even there we can remove any inappropriate content.  Though we do not consider ourselves to be a children’s website, we do take pride in being child friendly, both in our content and in our advertising.  We do not allow adult ads despite that they are quite common on television.  Our Facebook pages and Twitter pages are more of an open forum, and we do not monitor that content as closely.  That is an excellent place to get the opinions of our readership as opposed to the opinions of our editorial staff.

Golden Orbweaver snares Horse Fly

Black and Yellow Orb Weaver (male and female?)
Location: Milton, DE
August 7, 2011 9:27 pm
Heya Bugman!
My boyfriend and I found this gorgeous Orb Weaver while vacationing in Delaware this weekend. While we were taking photos of her, that black flying insect (any idea what it is?) got caught in her web. She was lightning-fast and had him wrapped up in seconds! A few hours later, we saw her snacking on her tasty meal. Bug on bug carnage!
We also caught a glimpse of a smaller spider nearby with similar coloring. The male, perhaps? Hoping you can identify that guy for us! Thanks!

Hi again Bruce and Ren,
The Black and Yellow Orbweaver,
Argiope aurantia, has several other common names and we generally prefer the name Golden Orbweaver.  That Fly looks awfully familiar, but we have been unable to correctly identify it at the time of posting.  It doesn’t match any of the Horse Flies we checked on BugGuide, nor could we match it to any Mydas Flies.  We will continue to research its identity.  We cannot say for certain if the smaller spider is a male, but this large female Golden Orbweaver looks to be filling with eggs.

As we were responding, we noticed you sent additional images and the smaller spider does appear to be a male Argiope aurantia.

Daniel:
It is definitely a large female horse fly, maybe Tabanus atratus.  The “white” abdomen could be an artifact of the reflection of intense sunlight.
Eric

Hey again Daniel!
Horse fly makes definite sense to us. They’re everywhere near the beach in Delaware, as my very bitten up legs and arms can attest to!  And Eric’s theory of intense sunlight is spot-on.  Another picture we have shows nothing but black on the abdomen, so it’s entirely likely that I just caught the right angle to have the sun shining off the shiny part of the fly’s abdomen.  As for the spiders, we’re shocked!  We were speculating that it might be the male due to the similar coloring, but he was so small we nearly missed him and his web.  It’s hard to believe such a large spider and such a tiny spider are different genders of the same species!  Do the males make the stabillimentum as well?  We didn’t notice one in his web.  We really appreciate your help with identifying our interesting critters.  And thanks again for your amazing website!
Bruce and Ren

Hi again Bruce and Ren,
This BugGuide image nicely illustrates the size difference between the sexes of the Golden Orbweaver.  In most species of Orbweavers, the female is the larger of the pair, and in some species the size difference is noticeably great.  We have not seen any photos of male Golden Orbweavers with a stabilimentum.

I have many photos from a trip to Bioko, Equatorial Guinea. I’ve been floating around this picture in hopes of identifying this spider but most of Invertebrates I photographed have been very difficult to ID. Please have a look if you can:

Please resend and attach the spider photo.  We cannot grab the image from FlickR and we want to post the image before we begin the research.

Here you go.  Could you please give attribution if you post the photo.  Would you like me to send all of the photos I have questions about?

Hi Nathanael,
This is sure one interesting Spider.  We agree it is most likely one of the Orbweavers, but we don’t even have a clue at the genus.  As you might have realized, researching African bugs doesn’t always produce satisfactory results.  We are posting your letter and image and we hope eventually we will get an identification.

Orbweaver traps Stink Bug in Brazil

Spider in Northeastern Brazil
Location: Northeastern Brazil
July 19, 2011 12:34 am
Hello, I have another little specimen from Brazil that I’d like to know about. I saw these little dudes every once in a while in a web that they make in between plants or branches. At first, they appear to have 4 legs but if you look closely they group their legs together in four groups of two. They sit in the middle of the web during the day and night and are VERY FAST when a bug lands in their web. I would pick up ants and throw them in and watch the spiders do their work, which was quite entertaining. One house that I lived in had around 20 of these in the back yard. I don’t know the Brazilian name for this one though. I googled pictures of spiders in Northeastern Brazil until I found the spider I was looking for. Here it is icon smile Orbweaver traps Stink Bug in Brazil Thanks a lot!

Orbweaver traps Stink Bug

Hi Jay21310,
This spider is an Orbweaver in the genus
Argiope, and it appears to have trapped a Stink Bug.

Thank you so much for the identification. After I received your reply I studied a bit more about the genus and also found out that they are harmless to humans unless molested, and if bitten, the venom is very weak. I always thought otherwise because of the brightly colored abdomen! I also found out that the venom contains Argiotoxin (ArgTX-636) is often gathered for therapeutic reasons. What an amazing species!

Just curious to know exactly what kind of spider this is? Found it in the garage today and thought it was odd since I lived in this area for 40+ years and never saw one like it. Color is hard to see in pix but the sliver part is highly reflective almost like a mirror and the green is day-glow neon. Built a 2 foot diameter web overnight and it wasn’t in my way so I left it alone. I know bright colors in nature means toxic or deadly to predators so what is this guy packing?
Thanks.

Hi Mike,
This beautiful spider is an Orchard Spider,
Leucauge venusta.  Many individuals also have bright orange spots.

Hello Daniel,
Thanks!  I don’t believe in killing stuff and I leave them where I find them; he’s made himself  a nice home in the garage and that’s where I’ll leave him.  Thing is though, I use the garage as my shop daily and didn’t want to leave something potentially hazardous in there.  I always say everyone needs a home & everyone’s got to eat so we welcome all who find their way here.  You should see the looks I get when I show people the bee houses and bat boxes we installed, but after they overcome their misguided fears (and watch me pet the bumblebees on their backs) they leave with a new found respect for things.
This isn’t my first time on your site; a few years ago you identified 7 spotted beetle larvae for me which we now anxiously await thier return to our foundation walls every April.  When they first appeared, I emailed pix to an exterminator to identify them and he said “I dont know what it is but I’ll kill them for you.”  That’s when I found your site and I called him back to let him know they were beneficial.  Good thing I found your site because after they turned into Ladybugs, our aphid problem disappeared.  Before the beetles arrived for the first time, we spent hundreds of dollars a year to rid the aphids and they still were a serious pest killing many of our plants each season.
Keep up the good work!  The knowledge you share really makes a difference!
Thanks Again,
Mike

Thanks for the update Mike.  It is nice to know we have been helpful.

Dear neanderpaul,
Thanks so much for submitting this gorgeous photo.  Many of our readers write in wanting to identify the shed exoskeletons of Cicadas, and it is nice to have your marvelous documentation of the actual molting process.  Your Cicada is one of the Annual Cicadas that appear each year, most likely a member of the genus
Tibicen.

Daniel,
Thanks so much for responding! It is VERY rewarding to get a complementary response especially when I know how busy you are and how many emails you must get. We do have these every year. The cicada killers make quite a living here! lol! I submitted a pic in ’07 of a wheel bug that still appears on your site. I really hope you post this cicada pic. It is so cool to have a pic featured on such a cool site! Thanks again so much for your site and for responding!

Immature Golden Orbweaver

Might be a Silver Orb Weaver?

We get a lot of orchard spiders and gold silk orb weavers, but this guy is different. I can’t seem to find clear pictures of a Silver (Argiope argentata) to compare him to. What do you think?

Immature Golden Orbweaver

Dear Red Chloe,
We are trying unsuccessfully to put a dent in all the identification requests that were sent to us in the past week while we were out of the office.  This is an immature Golden Orbweaver,
Argiope aurantia, which you may compare to this image posted on BugGuide.  The Stabilimentum that this individual has woven into its web is distinctive, though the pattern changes as the spider matures.  The Stabilimentum is thought to act as a camouflage for the spider, though its exact purpose is not clearly understood.   Many members of the genus Argiope spin a stabilimentum and this has given rise to the common name Writing Spider.
