I think this was actually with a wasp collecting food for its nest. The wasp would collect a caterpillar, leave it just outside the nest and then head inside the burrow to check it was safe before taking the prey inside. But when the caterpillar was moved while the wasp was in the burrow, it would take the caterpillar back to the same spot as before then go inside to check the nest again. This pattern couldn't be broken.
