The new queen ant which has fled the nest on its nuptial flight seems to be more interested in the ornate ball set atop the post of my decking. She seemed to be eating the decking oil (see image directly below) I had treated it with, which I have seen other ants do in the past. She was also a very clean queen, for she was always grooming herself. She must have been up there for at least 2 hours, and seemed very reluctant to leave.
