帝王蝶(Danaus Plexippus)似乎放弃了其他Danaid蝴蝶典型的化学求偶，而是使用强制交配系统。女性被描述为使用抵抗行为来回应男性的胁迫。我们对君主性别选择的大部分理解是基于对地面上发生的交配尝试的观察，但最近的研究报告称，在树冠上频繁进行交配尝试。我比较了地面上的交配活动和树冠上的交配活动，发现在异性交配尝试中，地点并不影响交配结束的可能性。这表明，更容易获得的地面尝试数据可能合理地近似树冠内的交配活动。地面尝试的结果受到植被结构和雄性相对于雌性的位置以及交配尝试地面阶段开始时的地面位置的影响。我的观察表明，蝴蝶的位置可能与雄性搜索策略有关。目前尚不清楚所描述的抵抗行为代表的是女性还是男性的控制。然而，数据确实表明，尝试的结果同时受到行为和生态的影响：雄性搜索和捕获策略可能会影响交配成功，而人类对栖息地的影响可能会影响越冬地点的帝王交配活动。
Monarch butterflies (Danaus plexippus) appear to forego the chemical courtship that is typical of other danaid butterflies, and instead employ a coercive mating system. Females have been described as using resistance behaviors in response to male coercion. Much of our understanding of sexual selection in monarchs is based on observations of mating attempts that occur on the ground, but recent studies report frequent mating attempts in the tree canopy. I compared mating activity on the ground to that in the tree canopy and found that, among heterosexual mating attempts, location did not affect the likelihood of ending in copulation. This suggests that the more easily obtained data on ground attempts may reasonably approximate mating activity in the canopy. The outcome of ground attempts was influenced by vegetation structure and the position of the male relative to the female and the ground at the start of the ground phase of the mating attempt. My observations suggest that butterfly position may be correlated with male search strategy. It remains unclear whether described resistance behaviors represent female or male control. However, the data do demonstrate that attempt outcome is influenced by both behavior and ecology: male search and capture strategies may influence copulatory success, and human-induced changes to the habitat can influence monarch mating activity at overwintering sites.
