We made this bug hotel about a year ago at a local Family Fun Day. Yesterday, the little ones watched the busy lady birds for ages. We also brought ladybirds from other parts of the garden in to play. It could do with a bit more leaf-like stuffing, but we didn't want to disturb the creepy crawlies. One benefit of this design is that you can see the bugs better than in a woodpile on the groundand there is not as much risk as squashing while you are "observing". I did still have to restrain a little, curious, one-year old finger a bit!
