考虑到已知的防御属性的植物，和其他可以合理地假设，导致描述两种替代的攻击策略的食草动物，称为隐形和机会主义，以对付植物的防御。隐身的食草动物表现出适应性，以尽量减少损害和防御反应的食物植物。另一方面，机会主义者利用损害植物防御能力的情况，例如身体压力和食用植物后天抗性的丧失。此外，机会本身显示适应，如大规模攻击行为，强调粮食植物。草食动物物种低，相对不变的人口水平可能是隐形的，而那些可变的人口水平可能是机会主义的。食草动物的阶段变化可能是两种策略之间过渡的结果。有人建议，草食动物物种之间的相互作用更好地理解在干扰和便利比竞争方面。
A consideration of known defensive attributes of plants, and others that can be reasonably postulated, leads to the description of two alternative offensive strategies of herbivores, termed stealth and opportunism, to counter plant defenses. Stealthy herbivores display adaptations to minimize damage and defensive responses of their food plants. On the other hand, opportunists take advantage of circumstances, such as physical stress and loss of acquired resistance of food plants, that impair plant defensive capability. In addition, opportunists themselves display adaptations, such as mass-attack behavior, that stress food plants. Herbivore species with low, relatively invariant population levels may be stealthy, whereas those with variable population levels may be opportunistic. Phase changes in herbivores may be the result of transition between the two strategies. It is suggested that interactions within and among species of herbivores are better understood in terms of interference and facilitation than in terms of competition.
