Spiders seem to be everywhere this fall. There are dozens of spider webs on my deck; each morning, I destroy a new web as I leave the house. It seems like every time I go outside, I wipe spider silk from my face. And it’s not just my yard—several of my friends have noticed lots of spiders recently, too. I wondered if we’re experiencing a bumper year for spiders, so I asked a few arachnologist friends about it.
