Shinobi Ageha

are a species of butterflies in Jiraiya's novel, read by Tsunade in her Infinite Tsukuyomi dream.

In a warm season, they usually appear near to the village where Kaya and her family lived. According to Tsunade, the butterflies' powdery scales stimulate the flow of chakra and are therefore used as an ingredient of Military Rations Pills.

The butterflies also seem to be directly related to the usage of the Masked Man's Eight Trigrams Grid Palm, as both Hinata and Neji Hyūga noticed a presence of chakra, and during every encounter with the butterflies, the jōnin teamleaders were affected by the technique.

Trivia

 * When Konan used her Dance of the Shikigami technique to guide the genins' way to their teamleaders, her butterflies took on the form of Shinobi Ageha.
 * "Ageha" (揚羽) is the Japanese name of the "swallowtail butterflies".
