In the English tradition of collective nouns, a group of hawks (yes, applied to birds but I've extrapolated) can be a kettle or a cast. It is safe to say I have certainly had a cast of Hawk-moths in the garden this year, with many nights with multiples of several species in the trap.
Whilst many of the vernacular names in the moth world can leave one bemused as to their origins, this one certainly fits into the 'no-brainer' category...such a beauty. I had two in the garden trap on 15th July, nominate form and f. corylaria.
The diminutive moth that goes by this name has been turning up on the garden over recent nights, always a treat...if it wasn't for the scientist in me, I might use the word cute here, but I'd better not...
No need to avert your gaze, simply a quartet from the garden trap over the last few days with one thing in common, although the interpretation of Buff on each one tends to vary.
