Looking at the original article, it appears that the most spider like decoy photograph was chosen based on the appearance to humans - i.e. one with 8 legs which presumably you counted just as I did.
What appears spider-like to a fly, could be dramatically different - I'm imagining the process of trying to count appendages through a compound eye with a fly's brain and in the absence of the cultural system of symbols we use to represent numbers, etc.
