Comments & ID Thoughts

Not certain. Believe it may be a red widow or brown widow. But, brown widow eggs don't match. As shown in picture, her egg is smooth, round and dark brown. Her body, she has reddish legs and a dark abdomen. Sometimes the abdomen looks dark green, sometimes it looks black. When feeding she feels the vibration of the bug, sneaks up on it and seems to bite quick. After the prey is immobilized, she wraps it in a little silk and pulls it back to her corner to feast. She is pretty inactive, mostly barely pokes out of her corner to hang upside-down and watch. Please, help me id her.

I’ve seen a few pictures* that show adult females with their spiderlings, so the eggs should hatch within the mother’s lifespan. *image of female with spiderlings: https://images.ala.org.au/image/proxyImageThumbnailLarge?imageId=0fcdc9cb-fe70-4c9b-8b0e-5223723d352c Unfortunately, I can’t find any resources giving the lifespan or development period of Nesticodes rufipes. They are the only species in their genus and not well studied. I was able to find some information on the lifecycles of two spiders from closely related genera, which I have presented here: Steatoda grossa: “A well-fed female can lay three or more egg sacs each year. Each egg sac typically… Read more »
