Autumn is here and before winter arrives, insects and arachnids have some important work to get done. In the meantime, we can enjoy the beautiful handiwork of orb weaver spiders which is especially visible this time of year. On this episode, entomologist Zach Schumm of the Iowa State University Plant and Insect Diagnostic Clinic joins us to talk about orb weaver spiders. He discusses their beautiful work and how they prepare for winter.

Some Iowans spent a lot of the summer wishing for rain, others spent the summer wishing the rain would stop.
