I was wondering if you could help us identify the spider we found outside our door today?

Grass Spider

Hi Michelle,
We believe, because of the large, prominent spinnerets at the tip of the abdomen, that your individual is a Funnel Web Spider in the family Agelenidae, and a Grass Spider in the genus
Agelenopsis, and you can compare your individual to this image from BugGuide.  According to BugGuide:  “They also have two prominent hind spinnerets. A spinneret is a spider’s silk spinning organ. They are usually on the underside of a spider’s abdomen, to the rear. On many spiders, the spinnerets cannot be seen easily without flipping the spider over; however, with Agelenopsis, the spinnerets are readily seen without having to flip the spider over. Agelenopsis spp. also have somewhat indistinct bands on their legs.”
