I think it's best to start for non Bee keepers with a short explanation of a basic hive structure. Shown below is a French Dadant Ruchette which is basically a small starter hive and is exactly the same as a full size Dadant hive in design, Dadant being a style of hive.
The box structure at the bottom is called the Brood box which is where the bee colony lives.
Next with the hole in the middle is the Crown board or the cover that goes over the bees. The hole in the center is for placing a syrup feeder over or for placing a block of fondant for the bees to eat. When not in use it is normal to close it with a small cover.
Finally standing on edge in this photo is the outer metal covered weatherproof lid. All very simple really.
From time to time I lift the outer lids on my active hives to check everything is OK and as it's quite common to find various creatures that have made it their home I thought I'd take a few photos over the last week to have a reference for the future and of course a bit of winter fun.
