About 40 years ago, Mr Katsuno got many non-native fireflies from firefly dealers in other areas and then released them into the Matsuo-kyo area in this town. Since then, government officials instructed by Mr Katsuno have bred many non-native fireflies in the field, so native fireflies seem to have gone extinct in the Matsuo-kyo area. The town government has tended to conceal this fact.

The ratio of non-native fireflies has also increased in another area in this town. I have often asked the town government to protect native fireflies, but they (government officials and the mayor) have ignored it. They say to me that if the number of fireflies increases, it does not matter whether they are native or non-native, because even non-native fireflies are helpful for tourism bringing money. I never agree with their opinion. I think local governments are generally required to protect biodiversity. One of the reasons is that Japan has ratified the Convention on Biological Diversity. However, the Tatsuno town government has been neglecting it. Now our research on Tatsuno fireflies is being stopped by this local government, because this government is unwilling to admit that non-native fireflies are spreading.

Now I ask you, “What do you think of the action of the Tatsuno town government?”
