The Lepidoptera Group studies and records butterflies, macro-moths and micro-moths in Yorkshire. In partnership with the Yorkshire Branch of Butterfly Conservation, the Lepidoptera Group publishes the annual Butterfly and Moth Report which is distributed to all YNU members. 

To discover which butterflies can be found in Yorkshire, and in which vice-county they have been seen, look at the Checklist of Yorkshire's butterflies.
