Insect Hotel

No idea if this is called that everywhere, but insects can hide in this house. Butterflies, solitary bees and wasps and ladybugs make use of it. A week or two ago all the holes in the hotel were still open. No idea who checked in, but there's life in it.
By the way, you have to look carefully for the right material for an insect hotel: preferably no treated wood and a good shelter to keep the shelter dry. If it gets moldy due to moisture it will do more harm than good...
