King of the beetles

At the back of room 112 in the basement of Stone Hall, an unmarked door leads to a kind of beetle Narnia.

Behind the wooden door is one of forestry professor Diana Six's beetle labs. This one is dubbed the "dirty lab" because it's where bark beetles chomp on chunks of ponderosa and lodgepole pine, sawdust littering the window sill.

Careful observers may notice small, scattered beetle carcasses — ones that fled their bark nests for the light and failed to escape.
