Brimstone moth (Opisthograptis luteolata) in the bathroom at night
Sadly I don’t see many moths these days but the other night I noticed this medium-sized yellow moth perched on the bathroom tiles. I caught it in a glass and tried to make it go out through the window but of course it came straight back, attracted by the bright light. It soon disappeared behind a light fitting and I have not seen it since. I looked it up and it is a common British moth, the brimstone moth (Opisthograptis luteolata).
This reminded me that I saw another moth back in the heady days of July but forgot to blog about it at the time…

The medium-sized moth was spectacular but turned out to be an invasive species accidentally imported from south-east Asia. It is known as the box-tree moth (Cydalima perspectalis) and was first seen in Kent in 2007. It has now spread through southern Britain. The larvae feed on box-tree foliage.
I did encounter a third moth over the last month, but was so keen to remove it from the house that I did not take a photo. It was a very dark shadow on the curtain net one night and turned out to be a large Mormo maura, the old lady moth or black underwing, It looked very sinister. I caught it in a glass and released it under a street light.

Although I didn’t snap it this time, I found that I had taken this picture of an old lady moth on an outside wall on July 18, 2011…
