Here are 2020's earliest sightings of resident and common migrant butterflies, as reported to Butterfly Conservation.

The first Painted Lady of 2020 has been reported - a newly arrived immigrant or a late survivor from last year?

To count as first sightings, butterflies must be seen outside and be active (i.e. not in hibernation). If you are confident that you've seen a butterfly species in the UK this year that has not yet been reported below, please contact @email. You can follow all the latest sightings, as they happen, on Twitter @RichardFoxBC or on Butterfly Conservation's Facebook page.

If you would like to get involved with butterfly recording, not just for first sightings, but to contribute to our assessments of UK trends and to underpin conservation, you can download our free recording app or find out how to take part.
