Someone gave me a black plastic thing, about 6" high and says hive top on it. It was with a bunch of shallow supers they gave me. It has looks like 2 deep depressions in it with a screen over an opening down the middle. Looks like it has never been used. What is it? I can get my wife(the computer tech in the family) to do a pic. if i have to. Got a picture of a bee on it and fits on a super so I guess it is bee stuff.
