What's That Bug? does not endorse extermination

Golden Orbweaver perhaps

Mammoth bee-looking-spider
November 16, 2009
We stepped out of our house here in Pasadena, CA to go for a walk. In front of my neighbor’s house, we saw an insect moving on the sidewalk like Addams Family’s “The Thing.” You can hear it walking on the cement. I assumed that it might move fast when we had got closer. Instead, it moved slow, and when we had gotten closer and it stood still. It didn’t raise it’s legs in defense like some bugs. The head was golden yellow, the body yellow/brown, and the end was striped yellow and brown. We left it alone, came back, and it was ran over (probably by a bike). My lady said there was four legs; I thought it was three because it looked like a bee, but it didn’t have wings. Every body part was thick, like it was taking steroids. I left it at night, came back in the morning, and it was gone. I need your help. I’ve not seen anything this big since Mexico. I’m having a baby soon and would like to know what’s crawling around my neighborhood. Any help would be awesome. I drew four legs, but it might be three legs.

Sketch of Golden Orbweaver, we believe

Dear Andres,
Though your sketch is lovely, it makes it difficult to be certain of an identification.  We are guessing you encountered a Golden Orbweaver, Argiope aurantia, a harmless spider that builds a circular web in the garden.  The spiders are quite helpless if knocked out of the web, and they will not leave their webs to hunt, preferring instead to snare flying insects that become trapped.  Golden Orbweavers pose no threat to humans, despite the large size.

I found this spider hanging out on my front door when my sister came to visit today. I grabbed my camera so I could try to identify it.

Hi Marie,
Your beautiful spider is an Orchard Orbweaver, Leucauge venusta.  You can find more information on BugGuide.

Marbled Orbweaver and Suggestion

suggestion
November 10, 2009
I’m wondering if any of the other WTB addicts out there would agree with the idea that it would be cool to eliminate the bug’s name from the title of each submission, so that we can test our knowledge when we see the pic? Obviously it would be left in the body of your response.
Here’s a spider pic (because apparently I can’t submit a Q without one & because I’m not sure if this is a marbled orb weaver- it looks different than the one in my book).

Hi Vince,
Your suggestion does bring up some possibilities in our minds, most significantly the thought of pitching a game show to the animal planet.  Amateurs that we are, we do post a significant number of unidentified images and we rely heavily upon our readership to supply us with answers.   We are happy you needed to attach a photo as this is a color variation of the Marbled Orbweaver, Araneus marmoreus, that we do not often see.  It is well represented on BugGuide.

Marbled Orbweaver

New friend in Iowa

This little guy has taken up residence on our porch, is he doomed with the onset of winter just around the corner?

Marbled Orbweaver

Dear Worried,
We love your photo of a harmless Marbled Orbweaver, Araneus marmoreus.  It is a highly variable species, and BugGuide illustrates the variety quite nicely.

Update
Thank you
Fennecky, for bringing it to our attention that we did not answer the question “is he doomed with the onset of winter just around the corner?”  First off, he is not doomed, she is doomed.  This is a female spider.  Orbweavers do not live more than one season, and hopefully she will have laid eggs, ensuring a future generation.  If kept it captivity under optimal conditions, it is possible that a female Orbweaver may pass the year marker, but this would be a rarity.  The onset of a frost and freezing temperatures will probably end this gal’s life.

Dear mr,
We are uncertain what species of Orbweaver you have sent our way.  We couldn’t even say for sure if this is an Araneus.  Perhaps one of our readers can tell.  Your photos are amazing.  It isn’t unusual for female spiders to eat their mates.

*Must see* – Garden spider laying eggs
October 16, 2009
North CarolinaThis garden spider is the only form of pest control we use in our veggie garden – we find a pest, and into the web it goes. My 5 year old loves to help too, he named her “yellow butt”. She was well fed enough this season to produce two egg sacs, the second of which I was able to get these great photos of. I checked in on her every 5 mins for an hour and watched her progress. These photos are of her attaching the eggs to the base, but before she has encased them all in silk.

Hi Josh,
This spectacular species, Argiope aurantia, has numerous common names, and we prefer Golden Orbweaver.  Your egg laying documentation is a wonderful addition to our website.  Thanks for the contribution.

Orbweaver

Orange and Green Spider
October 11, 2009
I found this spider ON MY 8 MONTH OLD DAUGHTER! I have seen similar spiders outside our home at night but without the green diamond on the body. I live in Miami, Florida, USA. Please identify this spider so I can either find an exterminator or leave my worries behind!

Orbweaver: Araneus detrimentosus

Hi Cristi,
We quickly identified your spider as Araneus detrimentosus, a harmless Orbweaver, on BugGuide.  While we would hesitate to claim that this spider will never bite, we have not gotten any reports of anyone being bitten by a member of the genus Araneus.  If the spider was on your daughter, it was undoubtedly a chance encounter.  We would not trouble with an exterminator in this instance, and we truly believe that exposure to pesticides at a tender age would be far more detrimental to your daughter than facing the extremely unlikely odds that this spider, which is not very well represented in images and is probably not terribly common, will bite your daughter or a member of the family.

Dearest Bugman,
I just wanted to share a photo of this fashionable spider I found at my friend’s grandmother’s house on 8/16/09. I’m pretty sure it’s a Spined Micrathena.

Hi shutterbug,
Thanks for sending us your photo of a Spined Micrathena.  We posted an image earlier today, and it is very nice to have another recent example for comparison.

Banded Garden Spider

Golden Orb Weaver?
September 24, 2009
I just found this beautiful spider (about three inches long including the legs)… s/he built a web in the mint in my front yard. Am I right in guessing this is a golden orb weaver?

Hi there! Found this beauty on my porch in July 2009 in Southern NJ. Haven’t seen him before or since. Pattern is really cool, haven’t been able to find anything about him here or online.

Dear MYP,
It is quite unfortunate that this lovely green Orbweaver, Araneus cingulatus, does not have a common name.  You can see additional images on BugGuide.
