Species of moth

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. 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, also of the family Sphingidae, are known as "hummingbird moths" in the US, and "bee moths" in Europe. This sometimes causes confusion between this species and the North American genus.

Two or more broods are produced each year. The adult may be encountered at any time of the year, especially in the south of the range, where there may be three or four broods. It overwinters as an adult in a crevice among rocks, trees, and buildings.

The glossy pale green ova (eggs) are spherical with a diameter. They are said to look like the flower buds of the host plant Galium, and that is where the female lays them. They hatch 6 to 8 days after laying. and its hovering behavior, accompanied by an audible humming noise, make it look remarkably like a hummingbird while feeding on flowers. Like hummingbirds, it feeds on flowers which have tube shaped corollae. dawn, and even in the rain, which is unusual for even diurnal hawkmoths. M. stellatarum engages in free hovering flight, which allows more maneuverability and control than fixed wing flight, despite high energetic cost.

The hummingbird hawkmoth's visual abilities have been studied extensively, and they have demonstrated a relatively good ability to learn colours. They have a trichromatic visual system, and are most sensitive to wavelength in the range of 349 521 nm. They have been shown to discriminate a wavelength difference as small as 1–2 nm between sources. This discrimination is even more precise than Apis mellifera, or the western honey bee. Among other flower visitors, their visual system is similar to Papilio xuthus, or the Asian swallowtail butterfly, and Deilephila elpenor, the nocturnal elephant hawkmoth. Their larvae usually feed on bedstraws or madders (Rubia) but have been recorded on other Rubiaceae and Centranthus, Stellaria, and Epilobium. Proboscis length is thought to have been evolutionarily impacted by the length of flower feeding tubes. These moths, along with other moths, are in the family Sphingidae because their larvae were thought to resemble the Egyptian Sphinx.
