Note: The number wild in the field was counted semi-regularly by following the same path around the field. The number in column 5 is the maximum seen but the numbers were usually above 20 through out August and September. It is difficult to estimate the number that fed and emerged from the field during the year so no number is given. The numbers given in years 2006 and 2007 are guesses weighed by the activity seen.
