I have a spider protecting an egg sac in my hall. It's next to the frame of the front room and near to our coat rack.
I'm pretty sure it's a missing-sector orb weaver (aka Zygiella), as I've had lots of false widows in the house and they are bigger, don't have such banding on their legs and have a skull pattern on their backs.
I'm also pretty sure that false widows don't stay with their eggs, but Zygiellas do.
Can anyone confirm this? I'm loathe to destroy a nest that is so lovingly cared for by it's mother, if the spiders are harmless and she's been guarding it for days now.
