Hummingbird Hawk-moth

When you see one of these in the garden for the first time it is quite  an amazing experience....these moths really do look like humming birds. They are active during the day, incredibly agile and, as their wings beat so fast,  emit an audible hum. They do not survive our winters but migrate north from southern Europe. They are particularly fond of red valerian flowers, which we have growing against our house walls. Follow the link to report your sightings in the UK
