Winter draw(er)s on!

Decidely autumnal at Strump / Buck these days! Just a few Swallows getting a last feed before flying South...

If anyone has never been up close and personal with a Kingfisher, Strumpshaw is the place: you can't fail at the moment from any of the three hides! Also Otters, Chinese Water Deer and Buzzards are showing frequently.
I don't have any 'moff' books: anyone know what this is?
Obviously (?) a Hawkmoth, but quite small....
