The hummingbird hawk-moth is a small, day-flying hawk-moth. It is a summer visitor to the UK, migrating from Southern Europe in variable numbers each year. In some years, it can be common and may be seen in gardens, hovering like a hummingbird as it feeds on the nectar of honeysuckle, red valerian and other flowers. It can also be found along woodland edges, and on heathland and scrub. The caterpillars feed on various species of bedstraw, so the female adult moths lay their eggs on the buds or flowers of these plants.

The hummingbird hawk-moth has greyish-brown forewings, bright orange hindwings, and a greyish body with a broad, black-and-white 'tail'. Its hovering flight is a distinguishing feature; it flutters its wings so quickly that it can appear orange and makes an audible hum.
