How to identify moths
As bright as butterflies
Moths are often dismissed as brown and dull, but many species are actually bright and colourful. There are burnet moths with black and red wings, tiger moths with beautiful bold patterns, and hawk-moths that can be as large as your hand. Even the moths that are brown have intricate patterns and incredible camouflage. With around 2,500 species of moth in the UK, there's an amazing amount of diversity to be discovered!
Which moths am I likely to see?
Moths don't just come out at night. Some species fly during the day, especially on warm and sunny days. Others can be easily disturbed from their resting spot on vegetation, flying a short distance before settling down again. With sharp eyes or a bit of luck, you can even spy the more nocturnal species resting on bushes, trees, walls, or fences - especially if there's a light source close by.
