The difficulties of moth identification

Sometimes you can't see what's right in front of you. Having seen the orange underside of the moth below I spent a while staring at pictures of yellow underwings, until I realised I was barking up the wrong tree.

First Purple Clay of the year. Other firsts included Light Arches and Bright-line Brown-eye.

I spent some time looking at this small geometer (20mm wingspan) until I decided it could be Satin Wave - does anyone have alternative suggestions?
Following an email from Ian I was very interested to see the moth below.
It seems to have features of both Mottled and Willow Beauty. I suspect it's Willow which is common in my garden, but it is quite blotchy and the convergent crosslines which I usually look for seem absent. The hindwing and rearmost crossline aren't scalloped which points to Willow Beauty. The underside of which I was unable to take a decent shot, was quite well marked, unlike Willow Beauty. Always grateful for help!

  1. I think you are correct re the satin wave Adam - that`s a very good record of a scarce moth that is only currently known in the county from the Pembrey/Burry Port coast area. I may also have had it at Pwll - I can`t remember at the moment. Well done - another excellent moth for Gors Road!
    As discussed by email last night, I think that the last moth is mottled beauty - from the shape of the mid-wing line (the `upperwing postmedian costa`); also the hindwings are actually scalloped to my eyes.
