1 September β 24 May
the coastal calendar, unshifted
Pine and olive trunks; the sound is the whole coast from late June, and stops in September.
The song is only the males, only above about 22 Β°C, and it is the most reliable thermometer on this coast β a cool morning is silent. Everything visible about this insect happens in its last few weeks of a five-year life.
