Flash, I got you!

No, I have not tried to blind a southern oak bush cricket here.
This insect is actually attracted to light and can often be found in flats at night. Suitable period for this is late September to December.
Males reach a length of 11 to 13 millimeters, while females are 11 to 16 mm long.
The southern oak bush cricket cannot be confused with any other species in the Netherlands, because the adults have a characteristic appearance and are virtually wingless.
