I picked this up at an antique shop in Maine last year. The woman told me it was a "bee trap".

This is the front. It's hard to see but inside, there are two cones hanging from the top.

Here's the back...you can see the cones better.

This is the screening on the bottom.
I know I've seen these, maybe on e-bay, but not sure what they're original use was for. Drone traps?
