Some of the successful spiders here — outdoor ones, that is — have grown quite large. And the largest ones are the ones that have built webs on street lights, which attract bugs by the swarm.
Last week, while walking the dogs at night, we saw something quite large hanging from a web on a streetlight. It looked for all the world like a moth, but it was way too big to be one. Even if there was a moth that big, there's no way a spider's web would trap it. It had to be a bit of insulation or something.
A few nights later, it was gone. But something
was fluttering in the light. We could see it easily from 100 yards away. Was it a bat? A small bird? No, the movement wasn't right. It was very fluttery and quick. As we got closer, we could see its wings going very, very fast. It was moving too much to tell for sure, but it really seemed like a moth the size of a baseball.
Later, we discovered one that had landed, so we could get a good look and photos.
Here's another look, along with Stefanie's hand to give a sense of the scale.
I hope these things never start eating my suits!
