Orbweaver

Oval St. Andrew’s Cross Spider

Dear Tharindu,
Your spider is an Orbweaver, and we believe it is in the genus
Argiope.  Large Orbweavers are capable of biting people, but they are docile spiders that rarely leave their webs, and the bite is not considered dangerous.  Thanks to images posted to WongChunXing.com, we believe you have an Oval St. Andrew’s Cross Spider, Argiope aemula.  According to A Guide to Common Singapore Spiders on Habitat News:  “Unlike many other Argiope spiders, the abdomen is oval. Argiope spiders make webs which are suspended vertically 1-2 metres from the ground, the web of mature female spiders of this genus can be easily recognised by the X-shaped zigzag bands of white silk in the centre of the web.”

Noticed these (11) egg sacs in our Aloe barberae tree, and I have never seen anything like them in my life. I haven’t found the mama yet, but after looking around I am guessing them to be from the Bolas spider. LOL, I was ready to call the State bug authorities and have them terminated, but from what I read, they are harmless moth eaters so I will let them be. They are still a bit scary to look at.

Dear Gman,
We agree that these are Egg Sacs of a Bolas Spider, and we concur that the adult Bolas Spider is harmless as well as being difficult to find as they resemble bird droppings.

I just took a pic of a spider at my workplace and I have no idea what kind it is or if it’s venomous or not. I have included a clear picture of it

Orbweaver

Orbweaver

Dear Laura,
This is an Orbweaver or Writing Spider in the genus
Argiope, most likely the Banded Argiope, Argiope trifasciata.  It looks like an immature individual and that is its exuvia or cast off exoskeleton at the top of the image, indicating that it has recently molted.  Most spiders have venom, but that of the Orbweavers is not considered dangerous to humans.  They are reluctant to bite people, though a large individual might bite if carelessly handled.

Found this spider on the handle of my pool broom. We just moved to Florida, so there are a lot of new bugs! I’ve never seen anything like this spider, and it really creeps me out! Do you know what it is, and is it poisonous?

Dear Amity,
This is a harmless Orbweaver in the genus
Araneus, and we believe, because of the projecting bumps on the abdomen, that it is a Cat Faced Orbweaver, Araneus gemmoides.

Hello
We found this spider in the bushes next to my house in ladera ranch, Ca. (Southern California). Please let me know, so I can tell my son. Is it friendly?
Thank you

Dear Dennis,
As much as we feel the need to promote the benefits of insects, spiders and other bugs, we have a really hard time thinking of spiders as “friendly” but with that said, this Silver Orbweaver,
Argiope agrentata, is not considered either an aggressive or dangerous species.  Orbweavers are relatively docile spiders that generally remain in their webs, and they are actually quite clumsy when attempting to move about outside the web.
