About the UKMoths Website

Welcome to UKMoths, your online guide to the moths of Great Britain and Ireland. UKMoths has been providing identification help and information about Britain's moths for over 15 years.

What's UKMoths all about?

Traditionally, moth fieldguides have concentrated on the so-called "macro-moths", of which there are around 800 regular species. To study all of Britain's species incuding the often very interesting microlepidoptera, requires an expensive library of reference material.

The ultimate idea of the site was to illustrate as many species of British moths as possible and to provide this information in an accessible format. Over 2500 species have been recorded in the British Isles, and currently 2239 of these are illustrated, featuring 7098 photographs.

If you have good quality photos of British moths or lifecycle stages not yet featured on UKMoths and would like to contribute, please check the guidelines for contributors.
