When I set off for the dog walk this morning, one of my neighbours was standing in his front garden. He said he was looking to see if there were any Hummingbird Moths around. He claimed that they were rare but he'd seen 3 or 4 at the same time last year, that they favoured a blue shrub (a Ceratostigma) and they were like hummingbirds in the way they hovered over the flowers.

I was intrigued, so I searched for Hummingbird moths on UK Moth site. And nothing came up. Is he pulling my leg? (He likes a joke). Or is there really such a moth? If so, a photo or a link would be appreciated!
