Geoff Dicker sent me the following observations:
"Just to let you know that a late afternoon walk along the Avon at Whaddon on Monday 1st June produced :-
3 Scarce Chasers (2 male and one female)
Many White-Legged Damselfly, Banded and Beautiful Demoiselle.
Most of the activity was around the large patched of nettles opposite Monkton House either side of the bridge. As a relative newcomer to "dragon" watching I observed some interesting behaviour involving an Emperor dragonfly seemingly being mobbed by Banded Demoiselles similar to the mobbing of birds of prey by smaller birds. Is this regular behaviour I wonder?"
This mobbing behaviour is something I've only observed from larger dragonflies such as 4-spotted Chasers and Black-tailed Skimmers. Has anyone else noticed this from Demoiselles or other damselflies?
