280 days of Urbpandemonium #2

I laid on my back, looking up under a zoo exhibit with my flashlight. I was looking for construction weaknesses that might allow pests access. While I was under there I found this very busy cellar spider Pholcus phalangioides nursery. It's not clear if the female in the lower left corner of the photo is responsible for the many egg cases in the web, but I suspect that most of them are old and empty.

Cellar spiders are very common in dark and secluded indoor spaces. I encounter them frequently, and consider them to be beneficial allies who help me control flies and cockroaches.
