The first species was a Common Marbled Carpet. Here's a link to the UKMoths website. I know "my" moth doesn't look anything like the examples in the link, but they are apparently very variable!!
Common Marble Carpet
The second moth was another carpet species, this time a Red-green Carpet. Link here.
These two species take my "garden list" (sorry, you knew it had to happen, another list!!) to 4 species when added to the Large Yellow Underwing and Silver Y that I saw during the summer. Two links again; LWU and Silver Y.
Large Yellow Underwing
Silver Y on the Buddleia
Finally, before everyone nods off, here's a picture of a Sparrowhawk that's taken to eating the Goldfinch in the garden.
