Thought i would submit this report thinking it might be a location not commonly covered. During late morning cloud and drizzle it was warm enough for a few Small Heath to be flying. When the sun came out early afternoon the numbers exploded. Had i done a proper count there would have been over 100. Clouded Yellows also appeared from the grass. At least 30 =40. Also 10 Speckled Wood, 3 Small Copper and a Common Blue
