General comments Extremely local resident.
This species is extremely likely to be overlooked in many places, but the current emphasis on North Herts in the distribution map is interesting. All the modern map dots refer to the years from 2015 onwards; prior to these records it was last noted with us in the Stort Valley at Sawbridgeworth Marsh in 1991.  | Determination by Genitalia Examination Required | |
