Moth and Butterfly ID Course

Learn to identify moths and butterflies, and join us for a walk around our regenerative farm to survey and record the species we have here. Listen to an expert talk by National Trust Ranger, Nick.

Comprising of over 2000 species in Great Britain alone, moths and butterflies play a vital role in our ecosystem and are key indicators of climate change and the health of the environment. Moths and butterfly form the order called Lepidoptera, meaning ‘scaly-winged’.

They are an important part of the UK’s wildlife, they are highly sensitive indicators of the health of the environment and play crucial roles in the food chain, as well as being pollinators. However, butterflies and moths are also one of the most threatened groups of wildlife. Many species depend on a narrow range of plants or food types for their survival, this is why they’re such useful environmental indicators, but also why we’re seeing such dramatic declines in their numbers.

Most people think that the difference between butterflies and moths is that moths are always dull in colour and that they’re all night-flyers, whereas butterflies are colourful and can be seen in the day. However, there are also day-flying moths and they can be as vibrantly coloured as butterflies, such as the emperor moth.
