French Jura: Dragonflies

July 17-21, 2012:
The slow-flowing River Orbe at Bois d'Amont, 50 kilometres north of Geneva, has a good range of dragonflies and damselflies. Several male Downy Emeralds endlessly patrolled the riverside vegetation but were never seen to settle.

White-legged and Variable Damselflies were also very frequent here as well as the commoner Large Red and Emerald Damselfies. Unfortunately, possible sightings of Dainty and Southern Emerald Damselflies were never satisfactorily confirmed.

Well away from water in a woodland glade near Divonne-les-Bains, a beautiful Golden-ringed dragonfly perched on the vegetation. This was not a species which occurs in Britain but was the European Cordulegaster bidentata, much darker and with narrow pointed-ended rings around the abdomen.

A good day in Shropshire for Damselflies

June 4, 2011
Good warm sunny weather prompted a visit to Shropshire especially to look for White-legged, Variable and Red-eyed Damselflies. Localities near Atcham and Berrington were visited as these are places where all three are known to occur. White-legged Damselflies are nearing their northern limit here but neverheless are quite frequent amongst the dense bankside vegetation of the slow flowing River Severn. Many were seen today in various stages of maturing colour form but could be readily recognised by their distinctive white legs.

Below, two photos of an immature:




On a small pool near Berrington several Variable Damselflies were found, the distinctive ‘wine-glass’ shape on segment 2 helping to separate them from other Blues. Some of the males had the characteristic ‘exclamation mark’ bands on the thorax although this was not always the case as indicated in the common name.

Male Red-eyed Damselflies staked out their territories on the lily-pads and were especially aggressive towards other males.

Blue-tails were also frequent as were Azures and Common Blues. Large Reds were present but not so common.

Altogether 10 species were seen including Banded Demoiselles, two Broad-bodied Chasers and a distant Downy Emerald.
