Vampire moth?

It's big, but can't see any pointy teeth.

Looks like the Diamond back moth. It has invaded from the Continent and is devastating cauliflower and broccoli crops. Apparently it is resistant to pesticides.

horrible !!!

Pity that the pic isn't from above its a it difficult to see the markings although I don't think its the Diamond Back as that looks quite delicate and is long and thin at rest.

There's a moth called the death's head hawkmoth, with a picture on its head of an apparent skull. It's huge, but I don't think yours is that one.

Its been difficult to get a photographs and we don't want to disturb it. I think DH would recognise most native species so we think its foreign- interesting about the cauli and broccoli crops we aren't growing any veg this year and haven't got any neighbours doing so either. Nearby fields are cereal crops. I will keep a watch on it.

Its laid eggs!!while I was watching Versailles.

It looks like a lime hawk moth. We used to get them in the Nursing Home I used to work in. They are huge, and really spooked one lady when one flew in through her open window. here's a photo
