Thank you, Melissa, nice links! I didn't see any tube or trap lid; if I had known what this might be, I would have searched for these. Fascinating, I was actually unaware of non-spinning spiders. I am not an arachnophobe, on the contrary, I find them fascinating, probably because my mother always said we should never kill a spider, since they brought luck to the house; she was a nature-loving and wise woman.
