Meadow Brown (Maniola jurtina)
Another common species on patches of unmanaged grassland practically everywhere. As in many other butterflies the eye-spots are used to either frighten predators or deflect the pecking of birds.
Adults are seen from early June into September. Males are never as brightly marked as females but by the end of the season older individuals of either sex can be very faded and pale.
