Comments & ID Thoughts

I took this photo outside Lewis and Clark Caverns in Montana. Spider was under an inch across. It was on the ground. Perhaps an orb weaver?

The closest spider that I know of is the catface spider, Araneus gemmoides. It isn’t normally so bright yellow-orange and the projections aren’t so bulbous.

You might compare to genus Mastophora (Bolas Spiders). I have just not seen one so spiny
Yes, one of the orb weavers.

Thank you! I didn’t know that genus of orbweavers existed.
