Aeshna affinis (Blue-eyed Hawker/Southern Migrant Hawker)

First encountered by us in 2012 when we found a male on patrol at the Terres de Picodon, one of the premier locations in the Parc Naturel Régional de la Brenne.

Since 2010, they have been recorded in a couple of site on the UK’s south-east coast, including Wat Tyler Country Park in Essex. Aeshna affinis features in the BDS list but that list doesn’t appear to draw a distinction between truly resident species and migrants. However, it has been seen at Wat Tyler consistently since, as well as at a site in Kent and does seem to be spreading so I’m sure it is now resident.

[If you find distinguishing our Hawkers a little confusing see my comparison charts which should help.]
