在法布爾*的森林觀察飼育舍 / The Fabre Forest Observation and Nursery Centre

在法布爾*的森林觀察飼育舍（位於栗山町）人工飼育著日本的國蝶-大紫蛺蝶。栗山町雖然是這種蝴蝶的最東邊的棲息地界線，此地的大紫蛺蝶也面臨了絕種的危機。這裡也兼有自然教育的目的，會在用網子罩住的屋外放養羽化的大紫蛺蝶，一般民眾也可以進到網子內參觀。參觀最佳季節在7月。

The Fabre Forest Observation and Nursery Centre (Kuriyama Town) focuses especially on the Omurasaki butterfly which is commonly known as the Japanese emperor or the great purple emperor. The butterfly is recognized as Japan's national butterfly by Japan Insect Society. At this center, the Omurasaki butterfly is artificially bred. Kuriyama is the eastern limit of its habitat in Japan, and Kuriyama's colony faces extinction. This center also functions as an educational facility, so they exhibit the Omurasaki butterflies after breeding them in a big net tent outdoors, as well as different specimens, for visitors. July is a good time to visit this great facility.
