General comments: Widespread and usually common resident.
The species seems near absent from much of Middlesex - a surprising discovery that cannot be fully dismissed as under-recording. Though widespread and abundant in Hertfordshire, the records seem to suggest that this is a recent phenomenon, with very few reports from prior to 1990. Recorded in 30 (73%) of 41 10k Squares. First Recorded in 1937. Last Recorded in 2023. |
