Is it worth making (or buying) all those insect habitats. You know the things I mean. Bundles of bamboo. Flowerpots stuffed with straw. Logs drilled with different sized holes. The latest in bijou high rise insect houses with a variety of insect accommodation.
Obviously you see the odd spider running in and out, but do butterflies hibernate in their solar powered butterfly houses? Does that little bottle of pheromone really attract the clearwings?
Well it seems that give insects a enough holes, houses and habitats and they will find them and use them.
