I spent a few hours this afternoon looking for Banded Demoiselles along the river bank by Darley Cricket Club. I eventually saw a female but Ken had seen several including this male he photographed earlier in the week. Both Ken and Simon Roddis have seen Banded Demoiselles in this area in previous years but they appear to be in small numbers. They can be seen more reliably along Cromford Canal. It would be interesting to know if they occur further up either the Wye or Derwent.
