The moths above were photographed by Martin Starnes in his Surrey garden. He says: "I have now photographed thirty plus species in the house or garden in the last few weeks, most identified thanks to your website" - it's always good to know that the site is helpful.

The two Jersey Tigers above are from Emily Tutton, taken near the athletic (previously Olympic) stadium in Stratford, East London. She says the moth was "friendly and beautiful" and also manages to get a pose on her hand. She adds "I thought you might like the pictures as your site helped me to identify it!" (Always glad when the site serves its purpose.)
