Spotted amongst passion flowers at dusk. At first I thought the spider was dead - the higher one definitely is! It then moved and splayed it's legs. It looked as if it were 'fishing' and I assumed it had killed and eaten some of the other spider. Could this be a female having killed it's mate or just a clever hunter. Other photos on request.
