Camellias and Spiders

I have camellias! I came home from work and from across the yard I could see the flowers blooming. I also have this little buddy:

The Nursery Nazi came over not too long ago. Since she studies garden bugs for a living, she took a look at my yard. Fortunately, she said "Looks good. You have lots of banana spiders, so its good." I'm guessing it is because it they eat so many garden pests. Since she came by, I've be a bit more tolerant of the spiders, my organic pesticide.
