I’ve seen at least two species in the family. One species had strings of egg sacs or debris bundles on silk so thick and strong that I thought it was fishing line when I first saw and felt it. The bundles or sacs were weirdly strong and hard. The spider used them as decoys to confuse prey. They are shaped like the female. The females lined up on the strand with the sacs and stayed still. To find them I twitched the strands. That caused the mothers to move briefly a be visible.
Uloboridae seems to be correct, and I’d bet Uloborus glomosus is on the money as well. Thank you both! I’m pleased to have seen one, as I know they’re notable in the spider realm for being the only family without venom! what an interesting creature 🙂 Your stories are so interesting. I wonder if the silk might be more robust and strong to compensate for the lack of venom when it comes to catching prey. Oh and I’ve always been endeared by spiders who try to camouflage in their own webs (Cyclosa “trash line spiders” come to mind). Thank you… Read more »
