Ask Me About Spiders!

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!

I found this spider crawling about on my passion vine (Passiflora) tonight. Body size was 10-15mm.  It didn’t seem to have a permanent web.  San Diego, CA.

Hi, Cory! 

She’s in the ant-mimic/ground sac spider family, Corinnidae, and is Trachelas pacificus. …I was trying to think of a better way to phrase all that and not lose any info. Did I succeed? I don’t know.

Thanks for sharing more of your awesome photos! :)


Can you please tell me what kind of spider this is? It almost looked like an ant at first, then I saw the legs. [location: British Colombia, Canada]

Hi, Monique! Sorry for the delay!

I think your spider might be a leafcurling sac spider, Clubiona- different family entirely from ground sac spiders and the ‘yellow’ sac spiders- but I’m not 100% sure. I can’t make out enough details to say for certain, though that’s the best match I could find. I did think she was a Trachelas at first, but those aren’t found in British Columbia.

There are a couple species options, but I’m not going to attempt to get more specific than a genus. She’s totally harmless, though.

Thank you for sharing and for your patience!

Buggirl’s spider research

Hello there. I am wondering what type of spider this is. I am terrified of spiders but respect them as well. This guy just lounged at me twice while I was trying to unravel a hose for my pool. I am curious to know what it is and if its safe for me to ever go on that side of my deck again. I am in salem nh USA. 

Thank you,


Hi, Julie!

That pretty lady is a nursery web spider, Pisaurina mira. She’s harmless and likely appeared to be lunging at you because you got too close to her. She might even have an egg sac nearby, which would make her extra antsy. You can totally still use that part of your deck. :)

Here’s a good comparison photo, since your spider is demonstrating one of a few color and pattern morphs.

Thanks for sharing!

Banana spider?

Hi, Aaron!

That’s one name for that spider. She’s also called “garden spider” and “writing spider”. Her scientific name is Argiope aurantia. Like all orb weavers, she’s harmless.

Thanks for sharing!

Recluse vs. Brown House Spider? I live in Laveen, Arizona. I would like to know if this is the poisonous recluse spider. Thank you!

Hi, Marc!

Your pal there is a harmless huntsman spider, Olios giganteus, the Golden Huntsman. They get pretty big and, since they can flatten themselves fairly well, can get into places where people don’t expect to see spiders. I’m sure you’ve seen the image online of the spider poking out from behind a clock on the wall. That’s a huntsman. Also- and I know to the layperson this is semantics- spiders are venomous, not poisonous. Venom is injected and poison is ingested.

There are three species of recluse spider found in Arizona and none of them are the brown recluse. Loxosceles deserta is the most prevalent of Arizona’s recluses. But you don’t have to be concerned- the effects of recluse venom have been blown pretty far out of proportion. While it is true that recluse venom has necrotic agents in it, bites are rare and bites where venom is injected, rarer still. Spiders would much rather run from threats as massive as humans- they only bite when they feel threatened and when they have no means of escape. 

…Anyway, lovely Golden Huntsman you have there. :) Thank you for sharing!

Trying to identify this spider found in lower Michigan

Hi, Kylara!

That pretty lady is a harmless wolf spider, most likely Tigrosa helluo. This genus is made up of some of the larger wolf spiders in the US and was split off from Hogna in 2012 due to recently described differences.

Thanks for sharing!


spiderask can you tell me what this guy is? Southern California

Hi! So sorry for the delay!

I think he’s a Running Crab Spider, family Philodromidae, totally harmless. Since I can’t see the dorsal side of him, I can’t be sure as to which genus, let alone species, he is. Thanatus is a pretty good match, though. Compare this pic with your guy.

And here is a link to the genus Thanatus.

Thank you for sharing and sorry again that this took me so long!

Hello! Sorry for your trouble in submitting photos. Tumblr can be tricky.

Your spider is a male orb weaver, though I’m not 100% sure which one. I think he could be Araneus cavaticus, the barn spider. He’s totally harmless and was likely wandering around in search of a female. :)

Thanks for sharing!

This spider was on the wheel of a tire at about 3,800 ft. elevation at Wood Rat Paragliding & Parasailing Recreactional Site in the Applegate Valley of Southern Oregon…trying to identify & would like to know if it is poisonous…thank you, Janice

Hi, Janice!

That pretty lady is a harmless orb weaver, Araneus gemma. Though I haven’t seen such a brightly coloured morph before. 

Thanks for sharing!
