ファーストオークヒルでカヤコオロギが見られます。体長は1㎝ほどで、チガヤなどが生える明るい草地に生息しています。近年、草地の減少とともに、数が減っていると言われています。コオロギの一種ですが、翅は短く、鳴くことはできません。


I found crickets called "Kaya-Koorogi (カヤコオロギ)" in the First Oak Hill. They are about 4 cm in body length and live in sunny grasslands. In these years, as grasslands are decreasing, "Kaya-Koorogi" crickets are also reducing in their number. They are a kind of crickets, which are well known as a singing insect group, but they have short wings and cannot sing.
