Photo-Bombed!

I have mixed feelings about pictures like these.  I was shooting the Rain Lily---didn't even see the spider until I got the shot on the computer screen.  Love the bonus arachnid eating his breakfast, but, wish that I could have seen him in time to get some different shots so I would have a better chance to identify it.  Its coloring leads me to think it might be an Arrow-Shaped Micrathena, but I can't be sure.....
