I'm pretty sure it's Rustic

I'm pretty sure it's Rustic Shoulder-knot. Minor Shoulder-knot won't be flying for another month or two yet whereas Rustic Shoulder-knot is flying now

ID

You should re-add your ID with the scientific name included, then people can agree to it.

You're right about flight time - I didn't consider that. Well spotted.

Certainly not a usual RSK - if that's what it is. On first look the ground colour was completely wrong, shape was wrong and the markings didn't quite look right.

Looking again, it could certainly be a very atypical RSK.

Best wishes,

Douglas

Thanks for a all your help guys. Sorry to cause problems :-) Think it is more than likely RSK, thanks again

tricky

I'm still undecided on this - the antennae look to be very feathered, does that match Rustic Shoulder-knot? I can't find any other photos that show such feathered antennae.

Minor Shoulder-knot does have feathered antennae (in the male at least), and in Berkshire we have records starting at the beginning of June (building to a peak in July), but the wing markings don't look quite right for it.

Not sure!

Perhaps

someone should create a generic "noctuid" entry so the not-sure option can get a vote.

noctuid

Personally, I'm fairly happy it's an atypical RSK.

If you look closely at the markings, they do match that species - even if some of the more general features seem wrong.

Of course, the 'shoulder-knot' is clear on the image, so that limits the number of species possible. (off the top of my head I can only think of the two already mentioned that share this feature)

Not sure about the antennae, Martin. Male RSK do seem to have very slight pectinate antennae. I wonder if the antennae on this individual are distorted by the bottom of the pot/reflection? What seems to look like the wide antennae seems to continue beyond the moth, possibly suggesting it's the pot?

Best wishes,

Douglas
