Hummingbird Hawk-moths have been seen in a record number of gardens so far this season, particularly in the south and east of England. They were seen in 2% of gardens in June compared to an average of 0.5%. This species does not normally over-winter here, and the population is replenished each year by new migrants. As such, numbers can vary considerably from year to year. It has been particularly warm this June in eastern parts of England – more than 2.5°C above average according to the Met Office – and warm air drawn up from the south may have helped to carry them to our shores.
