Humming Bird Hawk Moth (Macroglossum stellatarum)
Wingspan 40 - 50 mm Not a native to the UK. Description: large proboscis and antenna, fan tailed thorax, orange hindwings and grey-brown fore-wings, marked with two black lateral stripes. Takes its name from the habit of flitting between blooms collecting nectar with its long proboscis, with a flight pattern resembling that of the humming bird. Although it has occasionally been known to overwinter in southern counties,this day flying moth is largely a migrant from the continent,flying any time from spring to October. A prolonged spell of warm summer weather and a southerly prevailing wind, can result in a fairly large presence of the humming hawk moths in the UK.
