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.

This beauty is spinning away in my side yard. She has a preportionally huge black abdomen with horns and light colored markings on it. The underside is cone-shaped and ridged.

Green Lynx Spider with Egg Sac

Giant lynx spider with egg-sac?!!
October 5, 2009
Hi,
I found this HUGE lynx spider at my aunts house last week. It was guarding what looked like an egg sac. The spider was about an inch long, with large mandibles, and big, hairy legs. The egg sac was about half the size of a gum ball, but shaped like a gumdrop, with a flat bottom and a domed top. The outside was golden brown, and looked like curly wool.  I thought you guys would like to see these pictures since you don’t have any showing an egg sac. I hope you enjoy these shots. Keep up the good work.

Hi Josh,
Thanks so much for sending in your photos of a Green Lynx Spider with its egg sac.  We actually have images buried in our archives of female Green Lynx Spiders guarding their eggs.

Non-Native Jumping Spider from Hawaii

Hasarius Andansoni
September 30, 2009
Okay, so I did send this little woman in for identification, but I went further and started to look more on my own. This is a female Andanson’s House Jumping spider. It took me a while to find because it isn’t a native species, but rather has been imported from somewhere in Asia. (I am not sure where specifically.) I don’t really expect you all to post this, but I figured you might like the photograph of this little spider to be identified, and seeing as to how you don’t always have the time… (Kudos for all that you do identify, not really sure how you do everything that you do.) Thanks for your time, and of course I shall be continuing to follow this page for anything unidentified to try and help out where I can.

Jumping Spider: Hasarius andansoni

Hi Tina,
We always say that getting our attention in the subject line is key to getting us to read letters.  That holds especially true for scientific names that we do not recognize.  With that said, we are thrilled to post your photo of an exotic Jumping Spider not endemic to Hawaii.  While we do not feel we have the necessary skills to accurately confirm or deny your identification, we can correct an error in your typing of the scientific name.  The genus name, or first name in the binomial, is capitalized.  The species name, or second name in the binomial, is always lower case.  Thanks so much for your submission and also your persistence in resubmitting your image with an identification.

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 Heather,
Your spider is not a Golden Orbweaver, but another species in the same genus, the Banded Garden Spider.

I sent an email a little while ago (today) asking about a spider in my yard. My mother has since emailed me this name. When I search your site, I see one similar, but am not sure if it’s the same as the spider I sighted in Oregon yesterday.

I’ll attach my pics again.
Thanks!

lynx or orbweaver spider?
September 25, 2009
My son, 6, found this spider hanging on one of our porch rails yesterday. We took some pics, but I don’t have a good identification system for spiders. He/she did seem to let out some sort of webbing when the cat knocked him from the step. No worries, this critter escaped safely under the porch! I know you can help us bug-geniuses!

Hi Sarah,
Thanks so much for attaching your images a second time.  Your spider is in the same genus as Argiope bruennichi, but it is the native Banded Garden Spider, Argiope trifasciata.  This is a harmless, wide ranging species in North America.  Argiope bruennichi is native to Europe.

Orbweaver: Araneus cingulatus

Green Spider, Red and White Patterned Back
September 25, 2009
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.
