This photo was contributed by Chris, showing hundreds of tiny spiderlings clustered on a door handle. Click for a more detailed view. I'm certain that these are baby Garden spiders, and those that make it will grow up to be the fat lumps you see in the middle of large orb webs later in the summer.

These massive clumps of babies are quite fun to play with. They're often all huddled together, but when you touch the huddle with a finger they explode out in different directions, then slowly work their way back.

Thanks Chris!
