It’s a flightless dark insect, known as field cricket.
It selects dry and sunny locations with short vegetation for its ‘home’.
The male digs a burrow with a platform at the entrance from which it attracts the female by its stridulation. It chirps during the day and the first part of the night, when the temperature is above 13°C.
Its peculiarity is a modified area on the male’s wings, (the ‘harp’), that permits to produce the sound to attract a female.
