Field studies of releases and recaptures of diurnal moths painted with yellow to resemble the edible tiger swallowtail and of black moths that resemble a toxic species of swallowtail produced these results: (i) A greater proportion of the black moths were recaptured; (ii) daily trapping for a week after each release showed that the black moths survived longer than the yellow-painted moths; (iii) an analysis of wing injuries shows that most attacks can be attributed to birds and that the yellow-painted moths were attacked more often, more vigorously, or more persistently than the black moths. These results are interpreted as showing a greater predation pressure on the yellow-painted than on the black moths and, therefore, as confirming the Batesian theory of mimicry.
(i)重新捕获的黑色蛾类比例更高;(ii)每次释放后持续一周的每日诱捕表明,黑色蛾类比涂成黄色的蛾类存活时间更长;(iii)对翅膀损伤的分析表明,大多数攻击可归因于鸟类,并且涂成黄色的蛾类比黑色蛾类受到更频繁、更猛烈或更持久的攻击。这些结果被解释为表明涂成黄色的蛾类比黑色蛾类面临更大的捕食压力,因此证实了贝茨拟态理论。
