We’ve seen this spider in our front yard in the same place for about three months. It seems to have a yellow outline of an hourglass on its belly. We’d like to know what kind of spider it is and if it’s poisonous.

Silver Garden Orbweaver

Dear Matthew,
This beautiful Silver Garden Orbweaver,
Argiope argentata, is considered harmless, though large individuals might bite if carelessly handled.  Most spiders are venomous, though very few have a venom powerful enough to threaten humans.

Thanks very much!  I’m glad it’s considered harmless.  We will leave it alone then.

Found this spider on the wall outside work today. Was pretty docile, and no web in sight, but quite pretty! Got several pictures from different angles, so I’m really hoping they’re good enough. I included one zoomed out photo to try and indicate scale. I’m thinking he must’ve been in one of the shipments we got this week since we’re setting up a new store, but either way he was an awesome spider to see!

Banded Garden Orbweaver

Banded Garden Orbweaver

Dear Laurie,
This is a Banded Garden Orbweaver or Banded Argiope,
Argiope trifasciata, and it is a local species for you as it ranges over most of North America.  Orbweavers mature in a single season, hatching in the spring and growing through the summer, attaining maturity and full size in the fall when they generally attract all the attention.  Like other members of the family, this Banded Garden Orbweaver spends most of its time in its web, unless the web is destroyed or it is pursued by a predator.  Orbweavers are perfectly harmless, though a large individual is capable of biting.  The venom should have little more effect than local swelling and tenderness.

Shamrock Spider

This is a harmless female Orbweaver, and though we sometimes have problems with species identifications in the family, we are confident this is a Shamrock Spider, Araneus trifolium, a species found throughout the northern regions of North America.  Here is a matching BugGuide image, also from Ontario.  According to BugGuide:  “Araneus trifolium female occurs in a variety of colors.”

Hello! I found this spider in one of the little hills in Cabo Pulmo. She was on her web and about 4 or 5 cm long. This was during late October. I would like to know the species and if it is venomous or not. Thank you!

Silver Argiope

Dear OBZ,
This Silver Argiope is considered harmless to humans, though like most spiders it is venomous, but the venom does little more than cause local swelling in the unlikely event a person is bitten by this non-aggressive Orbweaver.

This spider had a giant web that was catching mostly monarch butterflies in Central Texas. It appears to be some sort of a crab-like creature with 6 spikes around the top portion. The markings on the top are off-white with black, and on the bottom… look strangely reminiscent of the side of a monarch, with little dots. When it’s threatened, it hunches down and folds up into a nondescript little ball. What on earth??

I’m wondering what this spider is. Living in Mississippi, I have seen 3 of them so far and always around fall. This one is very large! The leg span could easily spread across my palm (about 3in across, 4in length), possibly grab around it a little. It’s abdomen is approx. 2-2 1/2 inches long, not including the head part. As you can see it seems to be a tan-ish color with yellow spots and yellow and black legs. Not sure if you’ve ever played Zelda, but the head part looks like the “skull spiders” on the game. We’ve just been referring to it like that Lol The web it’s made is huge, at least 3ft for just the circle. Happy to say it’s not running around or bugging anyone, yet. It’s web has been down a couple times (not by us, sticks and weather), it keeps rebuilding it right where it’s been, guess it’s eating well there. Is it poisonous? Should I be worried? I have 3 kids that love watching it but just want to be sure it’s safe.

Golden Silk Spider

Golden Silk Spider

Dear Kate,
Autumn is the time that Orbweavers, that only live for a year, reach maturity and as they reach full size, become much more visible.  Your individual is a female Golden Silk Spider,
Nephila clavipes, and though large individuals might bite if provoked and though they have venom, they are not considered dangerous.  Orbweavers are not aggressive, and they are relatively helpless outside of their webs, so they rarely leave the web.  Teach your children to respect this stunning spider, and we don’t believe you will have any need to worry.
