Banded Demoiselles

We are slightly confused. We spotted our first Banded Demoiselles of the year on the Hall Place' Flood Plain beside the River Cray. It is our understanding that the males are blue, the females green.

We decided to submit the sightings to iRecord: noting our understanding re. the colours. We were told: 'males can be identified in the field with care and experience. Female identification. only accepted from known Recorders or else needs confirmation from Vice County Recorder'. 

Fair enough we thought. Anyway: the Records have now been accepted without qualification! If we submit any more Records we will leave Sex as 'not recorded' with a note under the Comments.

Pictures show male (blue) and female (green): 



Update (7 June 2021): we have submitted and have had accepted, another three Records, for Demoiselles seen on the Upper College Farm, Landfill Site:
 


A Blue-Tailed Damselfly

Submitted to iRecord and had accepted, this (female) Blue-Tailed Damselfly, seen on the Upper College Farm, Landfill area:


Our first ever, Damselfly' Record.
