Plebejus argyrognomon is an endangered grassland butterfly species in Japan. In this study we focused on the parasitism rate of tachinid flies under different mowing management to obtain knowledge of this possible top‐down effect that has been largely ignored. We established three mowing treatments differing in the intensity of mowing, as represented by vegetation height. The results showed that the parasitism rate of P. argyrognomon increased with vegetation height; the parasitism rate in blocks subjected to the highest mowing intensity was 8%, whereas in blocks subjected to the lowest mowing intensity, the rate was 42%. We suggest that clarifying interspecific interactions is important for understanding how habitat management affects grassland‐inhabiting butterflies in general.

在不同水平的割草管理下Plebejus argyrognomon（鳞翅目：Lycaenidae）的寄生率

Plebejus argyrognomon是日本的一种濒临灭绝的草原蝴蝶。在这项研究中，我们重点研究了在不同割草管理下节节蝇的寄生率，以了解这种可能的自上而下效应的知识，而这一效应已被大大忽略。我们建立了三种修剪方法，它们的修剪强度不同，以植被高度为代表。结果表明，鼠尾草的寄生率随着植被高度的增加而增加。修剪程度最高的地块的寄生率是8％，而修剪程度最低的地块的寄生率是42％。我们建议阐明种间的相互作用对于理解栖息地管理通常如何影响草地栖息的蝴蝶非常重要。
