The png photo shows a European common gecko next to a cigarette lighter for size reference. The lighter is 55 mm long. From its size we can say that the gecko must be very recently hatched. The photo was taken 17 September 2018 in Madrid in my home. The patio and roof of our top floor flat on the southeast edge of Madrid has a permanent healthy <i>Tarentola mauritanica</i> population with small, medium and fully grown individuals. They occasionally venture inside.
