Orb Weaver sounds like a very mystic name for this giant spider. As usual, I stuck my arm into plants without looking around first and was startled by this very large spider on a very large web. I did some research and found that the nearly 4-inch spiders are nonvenomous and not aggressive. Like all wild creatures, it will bite if provoked.
The Orb Weaver is most active at night. In this photo the spider was preening itself, carefully cleaning each foot.
