I was outside doing some gardening this afternoon when I came across this moth, which I'm fairly certain I haven't seen in the garden before. I also had no idea what the moth was so I had to look it up.
Given the number of books in our house you shouldn't be surprised to find that I actually have two moth books; a photographic guide by Chris Manley and an illustrated one by Waring, Townsend and Lewington. While the illustrated one contains more textual information I find the photographic one easier to hunt through, so that was where I started.
It didn't take me too long to identify the moth as a Sallow (or in Latin Xanthia icteritia) the only problem is that the photographic guide suggests that common throughout Britain during September and October. Now I know the weather has been confusing the wildlife this year but we aren't even half way through August yet.
Fortunately the more detailed, illustrated guide came to the rescue. It says that there is one generation a year which flies September and October in the south and August and September in the north. So I'm guessing Penistone is in the north; thank goodness for that!
