    This spider was disturbed from it's hiding place when I was gardening. Its large eyes provide outstanding low-light night vision.Their compound lenses have an F number of 0.58 which means they can concentrate available light more efficiently than a cat (F 0.9) or an owl (F 1.1).The image is focused onto large,light-receptive retinal membrane (which is destroyed at dawn and renewed again each night). It catches its prey at night by casting a wool like cribellate silk net held by the front legs.

    Dear Cheryl, Thank you for getting down to the scale in which most of the world's diversity lives. The insight into the spider's vision and that they have "new eyes to see" each night is fascinating. This picture and the story will stick in my mind. Best, David
