The 2009 season began in April with an unprecedented six formations of crop circles. The first was a series of simple circles in a field of rape; then came a 350ft yin-yang symbol in a barley field near Devizes. Three ambitious formations were reported over the last bank holiday and on Tuesday this week a giant 600ft jellyfish was found in a barley field on Bill and Sally Ann Spence’s farm near Kingston Coombes in Oxfordshire.
