Picture of unidentified spider

Comments & ID Thoughts

My best guess is that this is a feather-legged orb weaver (Uloborus glomosus)! She made her home in my bedroom around February and recently became a mom (there's another egg sac not pictured that has spiderlings coming out already). She's about 5mm long (not including legs), tan, and has a kind of bumpy or angular abdomen. The reasons I thought she was U. glomosus were her shape, coloring, the "long" way she sits in her web with legs stretched forward, fuzzy-looking cribellate silk structures, and more recently, the shape/appearance of the egg sac. Would be interested to know what others think :)

I would love to see a pic of a close-up of hatchlings! Extra photos can be submitted as new photos, just please add a note. A siteuser’s photos can be seen together by clicking the username, then the camera icon. I’m impressed that she has two egg sacks. The reason they didn’t hatch at the same time is because female spiders store semen they received and release it onto… Read more »

I thought that particular photo on BugGuide was really close too. You’re quite welcome! I love that your Orbweavers’ web was made near a curtain with an orb web pattern! The spiderweb emoji is an orb web too. I think your spiders are a trashline species that are carefully made of dead insects, debris, and strong silk. If you lightly flick a strand with debris a spider might move toward the spot. It might feel like plastic monofiliment. That really confused me the first time I touched a trashline in a spider web. I wondered how fishing line ended up… Read more »
