I had something that looked very similar to this scurry across my carpet. It was a darker brown though, didn't seem shiny like these, and about 1 3/4 inches long. The best way I could describe it was an ant like head with a flat segmented body or what looked like it was segmented. It moved so quickly I could not get a photo. To be honest I don't know that it had those "glands" in the front legs, I didn't look at it very long. I was too anxious to get it out of the house. I scooped it up (it ran onto) a piece of paper and I threw it outside.I was afraid if it might be poisonous and bite my little dog.I've poured over your pages and this webspinner is the closest thing that looks like it. I live in a house in the San Fernando Valley just north of Los Angeles.
