July 12, 2011:
A visit to this small acidic lake a month ago resulted in only two Small Red Damselflies being seen; these were vastly outnumbered by the Large Reds flying at the time. Today the situation was reversed and Small Reds were present in good numbers although very localised. They are most easily separated from Large Reds by having red eyes and red legs. They are also smaller and are weak flyers. Male Small Reds and the females of the all-red bodied (f.erythogastrum) are not easy to separate although the latter are more robust. Females of the partially black f.intermedia were also seen here. Emerald Damselflies were emerging whilst at another small lake in the Conwy valley large number of Black Darters were flying.
