[8] One method the queens use to prevent this is covering the developing pupae in pulp, which acts as a reinforcer and makes it more difficult from predators to break open the pupae. Often, these structures incorporate sophisticated features such as temperature regulation, traps, bait, ventilation, special-purpose chambers and many other features. And many of these species sport large, powerful armaments such as tusks. (These coveted items are also dangerous, as birds can get them stuck around their heads.).
