The Pachygnatha is technically part of the Orb Weaver family. However, it does not spin a web and is a wandering hunter in the likes of the Wolf Spider. I cannot help but to think of this as the oxymoron of the spider world.
The spiders of the pachygnatha genus have a very large and round abdomen. Their legs are between dark and light brown. Sometimes, they may even have a transparent look, similar to the leaf-curling sac spider.
On the usually dark olive green or brown back, they have a distinctive white mark filled with brown patterns. These may seem like three small crosses in a row.
The largest species of the Pachygnatha genus grow up to 0,3 inches (7 mm). Male specimen are usually a bit smaller than female.
Being a part of the Orb Weaver family, this spider is not dangerous. Though it being a hunter, it may not be as timid as other Orb Weavers, its venom is not considered harmful to humans.

Grabbed up one of these amazing spiders yesterday in Hollis NH in Beaver Brook Trail. It was running across the trail path and I saw it amazingly because it blended in so we’ll with the leaf litter. I caught it in my baseball hat and got pics and video of it on my smartphone! I was at a complete loss as to why an obvious orb-weaving spider was hoffong it on the ground. Now I know what that’s all about ????
Is this a type of orb weaver spider?
Hello Jd, this is a male orb weaver of the genus Neoscona. Depending on where you found it, it might be a western spotted orbweaver (Neoscona oaxacensis) or an arabesque orbweaver (Neoscona arabesca).
Well, it’s definitely not this spider. Did you find it on its web or was it running around on the ground? If it didn’t have a web, it’s might be a wolf spider.
I found this spider in B’ham Alabama this morning. Can you tell me what it is?
