Hanworth

Ectemnius Sp

This has a silvery face thus not E cavifrons. The other suggestions were E literatus or E cephalotes.

Thanks to Tim Strudwick for comments.

So is there enough information in the photographs to do it.

The closest I could come was this top picture from Steven Falk's Flicker Album for Hogweed Fly Fox ♂︎ (Ectemnius literatus)
