We muck out our horse paddock twice a day. In the late summer and autumn, there are usually one to three dark-blue iridescent beetles sitting in burrows beneath the horse droppings. How do they get there in such a short time, which is perhaps 12 hours at most? Do the beetles come through the soil (which is often very hard and dry in the summer) or do they travel over the ground?
