Hi, I'm Tobias and I know a lot about spiders. Do you need an ID? Maybe you want to know more about those loveable arachnids.
Submit a photo or ask a question- I'm here to help you out!

Hi, Jon!

That beauty is a Noble False Widow Spider, Steatoda nobilis. Despite any of the bad press you may have read over the past few years, these spiders are pretty much harmless. Some people can have a reaction to their venom, but that’s true of any spider- allergies are everywhere. :) And in the rare instances that these spiders do bite, there can be effects similar to- but so much milder than- a widow spider bite. Though no one has ever died from a false widow spider bite.

Thank you for sharing!

Hi, I live in Boston MA and this spider has been living in my apartment window for several weeks usually only returning at night. It also seems to be getting larger. Any help with identifying it would be great, I thought it was just a regular house spider at first but those markings on its back stand out to me. Thanks so much!

Hey, Alison!

That gorgeous lady is a harmless orb weaver, Araneus diadematus. Called Cross Spider, Garden Spider and European Garden Spider, they’re easy to spot this time of year. She’s filling up and getting ready to lay her eggs, which will overwinter and hatch in the spring. The kids will spread out and go their separate ways soon after.

Thank you for sharing!

Can you please tell me what kind of spider this is?? It was found in south Carolina. Thank you!

Hi, Stacy!

They’re a harmless fishing spider, Dolomedes tenebrosus. Many people confuse them for wolf spiders, but they’re in a different family altogether. :) Wolf spiders are family Lycosidae.

Hi, Cecilia!

That cute little boogin is a jumping spider, Phidippus cardinalis. There are two or three other species of Phidippus with similar coloration, but P. cardinalis has the most white/grey on their face.

Thank you for sharing!

Hellooo.. I’ve been wondering for a while what these kind of spiders are and if there dangerous? They look like a daddy long legs but what is confusing me is…. They make webs…

And I didn’t think Daddy long legs could spin webs so it’s got me all confused. I see a lot of these in the bathroom ALL the time, especially in the corners at the top of the shower/bath. And the basement is infested with them which is why i’m so terrified to go down there and when I have to use the bathroom I walk in there with caution and for showers, I go over to my grandmas who lives behind me. Asking what these are and if there dangerous will probably help me out a bunch. Thank you! :) 

Hey there! Sorry for the delay!

I’ve been trying to compile a concise answer to this because I have a tendency to get long-winded. First, that spider is totally harmless. You have nothing to be concerned about. They’re cellar spiders but are also often called “daddy long legs”. The family name is Pholcidae and since I don’t know where you’re from and the photo is blurry, I can’t give you a definite genus or species. 

There are actually three animals that are called “daddy long legs”- one is a spider (pictured above in your submission), one is a harvestman (an arachnid, but not a spider) and the third is a crane fly (neither spider nor arachnid).

Thanks for sharing and I hope I’ve helped!

((Hey, so, I found this little guy a few days ago, and we see this type of spider a lot where I live (British Columbia, Canada (Okanagan to be even more specific)) and I was wondering, what species is this, and could it possibly be harmful/venomous? Also, I captured this wee fellow in a cup and set him outdoors, nice and safe, I was only too afraid to capture him by hand ‘cause I don’t know what it is >.< ))

Hello!

Let me first say it’s smart to not catch unknown spiders by hand. When you’re not sure which ones have a harmful venom, it’s a good idea to treat them with caution (and to release them alive, but a lot of you guys know that, now).

The best match for your pal is the Yellow Sac Spider, Cheiracanthium mildei. And don’t worry- it’s been proven that they do not have a venom that is medically significant. :)

Thanks for sharing!

I have two photos. I am in Owesso Oklahoma. I thing this one spider is a brown tranchula. It scared the crap out of my family because it was just out on the grass. 

The second one I found while opening s folding chair. I think that it is s black widow. 

I am from Iowa. I live in the country but I never see spiders like this. Thanks for looking at the pictures 

Hey, Jon!

She’s a harmless wolf spider and they can get pretty big, so the confusion is understandable. A long time ago in Europe, some species of wolf spider were called tarantulas until they were re-classified as the Lycosids they are today. That whole thing with tarantism gave wolf spiders a bad reputation for a while, too. From what I can see of her- the sun has washed some of her abdomen pattern out- I think she’s Hogna antelucana.

Thank you for sharing!

This tiny cutie was on my patio hanging out around the cat food bowl which tends to attract the Argentine ants.  It was rather active and uncooperative until I gave her something to eat.  She is feeding on a relatively newly emerged female fruit fly (Drosophila melanogaster) with vestigial wings (can’t fly).  For scale, the fruit fly is about 1mm long.  Normally I would apologize for the number of pictures, but it’s hard to apologize for something this cute.  San Diego, CA.

This spider was very golden in the sunlight and the pictures don’t really capture this color.  It looked similar to other jumping spiders that I’ve seen, except for the two prominent spots on the abdomen.

Hi, Cory!

Wow- what a cutie, indeed! They’re Sassacus vitis and as I was saving your awesome photos, I noticed you shared one of this species before. :) The really neat thing is that everyone has trouble getting that gorgeous golden color of the scales to show up on film. They also sometimes have a metallic green sheen to them.

Thanks so much for sharing! I had a tough time deciding which pics to include (as you can tell, I used more than half of them).

I found the spider on a railcar in chicago but I have no idea where the railcar came from 

Hey, Nathan! (A different Nathan than the one from earlier)

She’s a harmless orb weaver and looks like a Neoscona, the Spotted Orb Weavers. Going by the lack of pattern, she might be N. crucifera. Hard to tell from this lightly blurry photo, though.

Thank you for sharing!

I’ve noticed a few people confusing that conifer seed bug with stink bugs. They’re only distantly related- you guys are thinking of the family Pentatomidae.

There are 64 genera in the US alone, with more than 220 described species! So depending on where you’re located, you may be seeing different species of stink bug.
