Hummingbird hawk-moth – Macroglossum stellatarum
is a species of moth. 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.

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).

Moths in the genus Hemaris of the family Sphingidae are known as “hummingbird moths” in the US, and “bee moths” in Europe, which sometimes causes confusion between this species and the North American genus. It 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 forewings are brown, with black wavy lines across them, while the hindwings are orange with a black edge. The abdomen is quite broad, with a fan-tail of setae at the end. The wingspan is 40–45 millimetres (1.6–1.8 in).

In the southern parts of its range, the hummingbird hawk-moth is highly active even when temperatures are high, and thoracic temperatures above 45 °C (113 °F) have been measured. This is among the highest recorded for hawk-moths, and near the limit for insect muscle activity.
