Here's another Cobweb spider at work. This one's captured a firefly or some other related beetle. I hadn't really known much about Cobweb spiders until this past weekend's camping trip. They are spiders that spin disorganized webs and usually have rather round abdomens. A Black Widow is a Cobweb spider. It's difficult to nail down which species a Cobweb spider belongs to. There are several and they vary a lot within species as well.
