Butterfly Conservation

Saving butterflies, moths and our environment

Cornwall Branch

British moths are in serious trouble, according to the latest research about two-thirds of UK moths are declining and about a fifth of all British moths are losing numbers sharply enough to cause conservationists concern. Moths are seen as a good indicator of the general health of the environment, as different species occupy most types of habitat.


More information on moths can be found on the main Butterfly Conservation website.

Cornwall Moth Group is an independent group of volunteer enthusiasts, studying and recording British moths and migrant moths in the Cornwall. They work closely with Butterfly Conservation, both locally and nationally.

If you need help identifying a moth then the main Butterfly Conservation website may be able to help you. Click here to access the help pages.

The Garden Moth Scheme

This is a scheme for those who wish to get more actively involved with regular recording and learning about moths using a moth trap. All you need to take part in this survey is enthusiasm, a moth trap and a field guide. You just need to count the numbers of common moths you see in your moth trap, for one night every week from March to November. The list of moths to count consists of about 200 species, common in your area. Those that are difficult to identify are intentionally left out. This means that the GMS is open to recorders of all abilities. If you think you want to get involved go visit the website and don’t forget the facebook page where there is plenty of willing helpers for newcomers on identification and general advice. In case you are wondering what a moth trap is, its simply a tool for attracting, catching, identifying and releasing moths unharmed back into their natural environment.

Moth Night is on! 8-12 July

Moth Night takes place annually, the time varying from year to year. Participants are encouraged to see what moths are flying in their gardens and in the wider countryside, and to send in their records via the website. This is used to form a picture of how many species were flying around the British Isles, and to publish an account of the event in the journal Atropos. Public events form an important part of the event and are a great way to inspire more interest amongst the wider public.
