Funnel web spiders (Agelenidae) fit into the web building spider group. Their webs function as their primary hunting tool.
The picture shows its unique web design. It looks like a mass of silk with a hole, or funnel in the middle. Normally the spider sits at the end of the funnel waiting to pounce(印花粉) on a visiting insect.

With over eighty different species listed under nine genera, unless you have a picture of the spider by the funnel, many species in the United States can be difficult to identify.
They are commonly called grass spiders, and you can often see them, mostly the males, in your house or on the ground sharing territory with wolf spiders.
One general identification rule of thumb for funnel web spiders is to look at their tail end. Many species have extended spinnerets(喷丝头) and this differentiates them from wolf spiders.
