Information and Privacy Policy

Butterflies are in trouble. A third of UK species are threatened and three-quarters are in decline. Butterfly recording is the foundation for protecting these beautiful creatures. BNM Online enables you to contribute your sightings and help save butterflies. 

Your butterfly sightings will be stored within the iRecord website and passed onto the Butterflies for the New Millennium recording scheme run by the charity Butterfly Conservation. This long-running UK-wide scheme has gathered millions of butterfly sightings that provide vital information about how the fortunes of butterflies have changed over the decades. The sightings are used to understand the causes of decline and to inform conservation work on the ground to help threatened species. Many thanks for taking part!

Any records you submit using BNM Online will be displayed to other users of the iRecord website and be examined and verified by an expert before being added to local and national butterfly databases. Records may be collated and disseminated manually or electronically, including via the internet, for conservation, environmental decision-making, education, scientific research and other public benefit uses. Your butterfly records (but not your contact details) may be made publicly accessible on the internet.  

This following explains how any personal data you submit to BNM Online will be stored and used.


When you register for BNM Online, this will also create an account on the Biological Record Centre's iRecord system. This enables you to view, edit and download your records and see those submitted by other people. Your name, as specified in your BNM Online registration, will appear next to your records and will be viewable by other users of iRecord.

Your name forms an important part of each butterfly record and will be collated and disseminated with your records.
