Rapid environmental change can decouple previously reliable cues from important resources, causing specialized recognition systems to result in maladaptive behaviors. For native herbivorous insects, such evolutionary traps are often imposed by attractive invasive plants that prove harmful to their offspring. Despite the costs of ovipositing on a poor‐quality host, evolutionary traps are expected to persist when overlapping cue sets (cue similarity) link decreased preference for the novel, unsuitable plant with decreased preference for the historical or native resource. We evaluated the role of cue similarity in the persistence of maladaptive oviposition by a native butterfly on a lethal, invasive mustard. While the novel plant shares glucosinolate cues with at least one of the native hosts and the most abundant cue is a strong oviposition stimulant, we found that this cue was not a major driver of preference for either plant. Nor was preference for the two plants correlated, meaning decreased preference for the invasive mustard would not cause butterflies to miss potential oviposition opportunities on the superior native host. Instead, butterfly preference was modified by previous experience in a way that suggests that frequent encounters with native hosts in the wild may buffer butterflies against this evolutionary trap.

在维持持久的基于宿主植物的进化陷阱方面，经验可能会超过线索的相似性

快速的环境变化可以使以前可靠的线索与重要资源脱钩，从而导致专门的识别系统导致不良行为。对于天然草食性昆虫，这种进化陷阱通常是由证明对其后代有害的有吸引力的入侵植物造成的。尽管在质量较差的宿主上产卵的成本很高，但当重叠的提示集（提示相似性）联系起来降低了对新颖，不合适植物的偏好，而对历史或本地资源的偏好降低时，进化陷阱仍将持续存在。我们评估了提示相似性在致死性，入侵性芥末上的原生蝴蝶对适应不良的产卵持续存在的作用。尽管该新型植物与至少一个本地宿主共享芥子油苷线索，而最丰富的线索是强烈的产卵刺激剂，但我们发现，该线索并不是这两种植物偏好的主要驱动力。两种植物的偏好也没有关联，这意味着降低对入侵芥菜的偏好不会导致蝴蝶错过上等天然寄主上潜在的产卵机会。取而代之的是，蝴蝶的偏爱被先前的经验所修改，这表明在野外与本地寄主的频繁接触可能会使蝴蝶抵御这种进化陷阱。意味着对芥末的喜好降低不会导致蝴蝶错过上等原生寄主上潜在的产卵机会。取而代之的是，蝴蝶的偏爱被先前的经验所修改，这表明在野外与本地寄主的频繁接触可能会使蝴蝶抵御这种进化陷阱。意味着对芥末的喜好降低不会导致蝴蝶错过上等原生寄主上潜在的产卵机会。取而代之的是，蝴蝶的偏爱被先前的经验所修改，这表明在野外与本地寄主的频繁接触可能会使蝴蝶抵御这种进化陷阱。
