And the one that got away. I always take a "safety" shot first before opening the moth trap, just in case the moth escapes. And in this case, this individual did just that.

Obsidentify seems to think it might be a Leek moth Acrolepiopsis assectella, which it could quite easily be with so many alliums close by.

But sadly there is really no way to tell from this photo. Shame really as it would have been a new moth for my Port & Wey moth list.

I will just have to put the trap out again tonight!!
