Large Red Damselflies

19th April 2008, Saturday

The small pond at the entrance to the hide at Castle Water is the only reliable place on the reserve to find Large Red Damselflies which occur in small numbers. As the emergence period is fast approaching the pond was sampled yesterday for last instar nymphs, with restricted access to the pond a few were found. Photographs taken through a hand lens show two identification features, the square shape of the back the head (top picture), the bottom picture shows the distinctive pattern and shape of the caudal lamellae or gills.
