I don't know spiders very well, and when I spot one, they're unnerving enough that I'm glad I'm usually using a telephoto, rather than a small macro. That said, they fascinate me, and they're great subjects for photography. Usually when I see these long-legged and large-jawed Tetragnathids, they're hidden behind leaves in wetlands plants, but this one must have been hungry or in need of a more productive area. It can easily walk on lilypads, and it had no trouble walking a bit on water. The usual complement of damselflies that frequented this venue must have known the spider was in the neighborhood and steered clear of the venue.
