Mayfly emergence

On 15th July at Broom GP I found millions of tiny Mayfly exuviae on the plastic protectors surrounding the seedling trees. The trees were a metre or more from the waters edge and one side of the plastic was completely covered by them. There were also Common Blue damselfly exuviae on the protectors up to five metres from the water. The sheer numbers indicate that these pools are alive with invertebrates. Photos by Steve Cham
