The hummingbird hawk-moth (Macroglossum stellatarum) is a species of hawk moth found across temperate regions of Eurasia. The species is named for its similarity to hummingbirds, as they feed on the nectar of tube-shaped flowers using their long proboscis while hovering in the air; this resemblance is an example of convergent evolution.
The hummingbird hawk-moth was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. As of 2018, its entire genome and mitogenome have been sequenced.
The hummingbird hawk-moth is distributed throughout the northern Old World from Portugal to Japan, but it breeds mainly in warmer climates (southern Europe, North Africa, and points east). Three generations are produced in a year in Spain. There is evidence that the population in the British Isles is actively expanding its range, as numbers have been consistently increasing. In addition, it is believed that this population is becoming resident instead of migratory, as warmer temperatures due to climate change are allowing individuals to overwinter.
It is a strong flier, dispersing widely in the summer. However it rarely survives the winter in northern latitudes (e.g. north of the Alps in Europe, north of the Caucasus in Russia).
