Sort of a half lid...something I thought they might lay eggs on the under side. The whole thing is under a tin roof shed with open ends so I didn't figure on needing a complete lid to keep rain out. Just an old trash can I chopped on
Oh and thanks very much for the larvae offer! Any would be appreciated. I would imagine you have a lot around from letting that many go. Mine is not far from the woods, only about 40 - 50 yards. Today as I sat hoping to spot a BSF a big deer jumped out of the woods and ran along the edge of our sewer plant fence with caged dogs in the kennels right next to me going nuts.
