Moss Hornets pass through objects when attacking, but not when returning to the nest. This can get them stuck on walls/pillars/trees/etc until they get a new attack target.
Actually, it's a bit worse than I thought. It seems they can get stuck even when trying to attack, and sometimes even get stuck a long way away from the nest.
