Data from the British Trust for Ornithology (BTO) Garden BirdWatch survey, carried out by volunteers wideness the UK,
showa fourfold increase in the number of gardens recording
a Hummingbird Hawkmoth, making 2022 a record year.
These large, colourful insects are often mistaken for hummingbirds considering of the way they hover over flowers and use their long tongues to drink the nectar.
You are mostly likely to see a Hummingbird Hawkmoth in the UK during July and August. Last month, 5.2% of Garden BirdWatch gardens recorded a visit from a Hummingbird Hawkmoth, compared to just 1.3% in a typical year, while the proportion rose to 7.5% in southeast England. In Scotland, where the species is much rarer, it was reported from 1.2% of gardens, increasingly than three times the summer average.
Hummingbird Hawk-moths are particularly fond of pink and purple flowers like Buddleia, Red Valerian and Vipers Bugloss. Watching these plants on warm, sunny days is the weightier way to spot one yourself. Just squint out for a stocky moth with orange wing patches and woebegone stripes on its body.
The influx probably has its origins in the current long spell of warm, southerly winds that siphon the moths north from their Mediterranean strongholds. There is moreover a possibility that rising temperatures midpoint a growing number are worldly-wise to overwinter in the UK: in suitable conditions, Hummingbird Hawk-moths will spend the colder months tucked yonder in thick vegetation, a tree hollow or plane a garden shed.
While most Hummingbird Hawk-moths recorded in the UK are thought to be visitors from overseas, a number do successors here, laying their bluish-green eggs on plants such as cleavers (sticky-weed) and bedstraws. A single sexuality can produce as many as 200 eggs that grow into stripy untried caterpillars up to six centimetres long.
Rob Jaques, BTO Garden BirdWatch Supporter Development Officer, said: The striking visitation and unusual behaviour of the Hummingbird Hawkmoth ways the species attracts lots of sustentation from gardeners and nature lovers alike. Thanks to the resider scientists who record these and other species in their gardens, BTO Garden BirdWatch is worldly-wise to track the fortunes of the wildlife on our doorstep and learn how our untried spaces can weightier support biodiversity.’
He continued: ‘As climate transpiration has an overly increasingly obvious impact on the species we see virtually us, the data our wondrous volunteers collect has never been increasingly valuable than it is today.

NB Fatbirder’s garden in the lattermost southeast of England has been getting the moths since mid-May!
