学习在多种昆虫获取食物的过程中起着重要作用。为了提高觅食效率，访花昆虫可能会学习将花卉暗示与奖赏的存在(所谓的奖赏学习)或缺乏(所谓的非奖赏学习)联系起来。在许多昆虫分类群中已经证明了觅花时的奖赏学习，而访花昆虫的非奖赏学习只在蜜蜂、大黄蜂和鹰蛾中得到了证明。这项研究考察了蝴蝶Byasa Alcinous在不同颜色的人造花中觅食时的奖赏和非奖赏学习能力。这只蝴蝶表现出了这两种类型的学习，尽管两性蝴蝶通过奖励学习学习的速度更快。此外，女性通过奖励学习学习的速度比男性更快。据我们所知，这是关于昆虫奖赏和非奖赏学习的学习速度的第一个经验数据。我们讨论了当觅食花朵时，较低的学习速度对于非奖励学习的适应性意义。
Learning plays an important role in food acquisition for a wide range of insects. To increase their foraging efficiency, flower-visiting insects may learn to associate floral cues with the presence (so-called reward learning) or the absence (so-called non-reward learning) of a reward. Reward learning whilst foraging for flowers has been demonstrated in many insect taxa, whilst non-reward learning in flower-visiting insects has been demonstrated only in honeybees, bumblebees and hawkmoths. This study examined both reward and non-reward learning abilities in the butterfly Byasa alcinous whilst foraging among artificial flowers of different colours. This butterfly showed both types of learning, although butterflies of both sexes learned faster via reward learning. In addition, females learned via reward learning faster than males. To the best of our knowledge, these are the first empirical data on the learning speed of both reward and non-reward learning in insects. We discuss the adaptive significance of a lower learning speed for non-reward learning when foraging on flowers.
