The Butterfly Atlas 2021 is an exciting five-year survey of Ireland’s butterflies to produce detailed distribution maps of each species and to track populations through a series of standardised transect walks from across the country.  This year Heritage Week (17-25th August) coincides with both later emerging and later generations of many butterfly species and by getting involved in Butterfly Bash 2019 you can really help us map the distribution of Irish butterflies.  For Butterfly Bash 2019 please record all the butterflies you see over Heritage Week no matter how common or rare the species!  You can submit your records as normal through our recording form: https://records.biodiversityireland.ie/record/butterflies

This page shows the real-time progress with the submission of butterfly records during the Butterfly Bash 2019. If you live in or visit a part of the country where there are gaps in coverage (please see the blue and green 10 km squares on the map below), we would particularly welcome your butterfly sightings. As the week progresses, you’ll be see what species are being recorded, where they’re being recorded and which counties have the most active butterfly recorders!

Butterfly Atlas 2021 is a collaborative project between the National Biodiversity Data Centre, Butterfly Conservation Ireland, Butterfly Conservation Northern Ireland and the Centre for Data and Environmental Recording (CEDaR).
