This is a favourite of mine for a few reasons. It is a photo I actually planned, rather than one taken when the opportunity arose, and (unusually, for me ) it actually came out something like I had in mind. I also think as an image it wouldn't work nearly as well if it were any other UK species - certainly not one found around Bath.
It was taken in my local community wood, and I had noticed on previous visits that Commas were frequently attracted to some elevated brambles, which showed off their distinctive silhouette. I needed a photo to use as a closing image for the annual butterfly report I write for visitors to the wood, and had the idea of this as a quirky full-width image that would catch the eye.
If I ever come to own a stately home, I've decided I will install Comma-inspired gargoyles
