I was going to grab the molt when I first saw it last night. It was hanging near the top of her web. I could have grabbed it easily without much damage to her beautiful web. Nonetheless, I left it until the morn and now it's gone. I suspect she's dragged it, away from her regular web basking spot, and into the spagnum moss at the back - where she quickly drags her prey. Alas, this one's in the stash.
@Dave1969 Australothele Nambucca also are notorious for doing this, and every wild web Ive found always has a crunched pile of exuviae and probably eaten males hidden in a chamber or at the back of the web, closest to the entry
