Spider
This spider photo was sent in by reader Mark White, who has sent in spider pictures to us before. I don’t have an ID for this spider, but I feel like I should know it. The shape and coloration are somewhat distinct, and the web construction is very unique: It’s a well-organized sheet web, almost like an orb weaver, but organized in a net rather than a spiral. Then it is completely strung with tangling guy lines ascending to some off-camera surface. I have seen this kind of web construction before, but can’t for the life of me recall where. Furthermore, I seem to recall having seen it the other way up: with tangling descenders and the spider sitting on top of the web.
So it’s over to you, readers: what is it?
Also, I wonder what the white blurry shape is in the lower right. Another spider, perhaps? A discarded exoskeleton from this spider’s previous molt?
