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.
