Yellow Sac Spider

The Yellow Sac Spider is a common name for certain species of spiders in the genus Cheiracanthium, family Miturgidae. They are usually pale yellow in color and has a body length of 6 to 10 mm. Being nocturnal, yellow sac spiders are active in the night and search for their prey. They don't build webs. Instead they construct sacs in protected areas and that's why they are known as Sac Spiders. Their bite is believed to be venomous to humans. Therefore, they should be handled very carefully.

Beautiful pictures as usual! What was the size of this one? Large Sac spiders are known to cause a slight allergic reaction if bitten. And Spiderz rule is a great website! Thanks for sharing the info!

Hi!
I'm Calvin, a student from Singapore. I love your landscape and nature shots. I can see from the pictures taken that you are interested in insects and botany.

I am also into Photography and inspired to be a zoologist. Please do visit my blog, do comment on the pictures that you like and criticize on those you don't... This exchange of ideas would really help me a lot. Thanks!

Hi there, I stumbled upon your site after my roommate and I had a spider encounter in our living room. I think it might be a yellow sac spider but wondered if I could possibly send you a photo for identification. DO you help with that or could you recommend someone? My e-mail is grinalot@hotmail.com Thank you!
