SHELOB?

Wish I could have had a few more goes at this, but my camera pleaded "No Battery Power" after the very first shot.

The web is quite massive - guess the mass of the silk secretions would be greater than her body mass - so...

Did she build it little by little all by herself, sucking the juices out of competitors - there are three empty spider carcasses littered about, one of witch you can see just above her front door. Or?

Did she leap in fangs blazing & take over the joint?
