The first time I saw one of these at the Southern Rural Route, I was in awe. The University of Florida claims this spider is a Spiny Orb-Weaver, gasteracantha cancriformis. If you are of the female persuasion, it’s about the size of the finger nail on your index finger provided, of course, you aren’t doing that whole Cruella DeVille thing. If you know your way around the metric system it’s 5 mm to 10 mm long. For such small spiders, they weave large webs that contain tufts of silk which you can easily see in the top photo. The University of Florida seems to think these tufts “prevent birds from flying into them.” Doesn’t help me a bit. I’ve walked into at least two of them this week destroying all their hard work.
