First I think I have a Lesser Treble Bar - the angle of the bar isn't so clear to me but luckily it's a male I think and it looks like the Lesser Treble Bar.
I caught another Pyrausta last night - this time I managed to get a view of the underside - not particularly good but it seems to lack the costal band shown in the difficult moths pdf. So it looks like P. aurata. I didn't manage to get it out of the trap but I think it was the same one I saw last night with a single spot on the upperside.
Finally, just checking the final one is a Small Square Spot. Images in the various books seem to conflict on the amount of markings on the Square Spot Rustic but I'm going by the dark spot between the oval and the trailing edge. Is that correct?
