General comments: Immigrant.
Formerly an irregular immigrant, with annual occurrences in single figures, the number of reports has increased steadily from the start of the 21st century to the point where sightings are now more or less annual and in double figures. The grouping of Middlesex records seems odd. Recorded in 13 (32%) of 41 10k Squares. First Recorded in 1945. Last Recorded in 2023. |
