144923 Hummingbird Hawk-moth Macroglossum stellatarum Wingspan 45mm. A fascinating, migrant day-flying moth that hovers and sips nectar from flowers using its long tongue; the wingbeats create an audible hum. Resting moths sometimes sit on banks but are well camouflaged and hard to spot. Adult has brown forewings and an orange patch on the hindwings. Flies May-October. Larva is pale green with a lengthways white line, white spots and a small bluish ‘horn’ at tail end. Larva feeds on bedstraws. An occasional migrant visitor to Britain from mainland Europe; numbers vary from year to year but always commonest on the south coast.
