Upper Thames Moth Atlas

The fantastic online atlas for moths in Berkshire, Buckinghamshire and Oxfordshire was launched in spring 2022. It provides a wealth of information on the moths of our area, with maps, flight period charts, photos and much more.

In summer 2023 we updated the atlas to include micro-moths as well as macros, and to bring the records for all three counties up to the end of 2022. (Note that records cannot be added directly to the atlas, please add your records via iRecord or the other options listed here.)
