Why oh WHY do they have to GIRDLE the vines? What evolutionary advantage can this behavior POSSIBLY convey? I've lost two late-season Incense fruit to these guys now, and I just discovered that one cat snuck onto my Amethyst when I took it inside and nipped off two long (and actively growing) vines pretty darn close to the roots. I also lost a good six feet of Constance Elliott vine to this behavior back in the summer.
Why can't they just eat the leaves and be happy!?
