*Please note: The charts shown on this page are drawn only from casual sightings submitted to this website. They are therefore not statistically significant, but do serve as an indication of what’s going on in the Dorset butterfly world. The records from this website will be added to a lot more data collected throughout the year, and used to compile the five-yearly Butterfly Atlases for Dorset and the UK. These are vitally important because they show the location of species and, over time, measure distribution changes and the possible effects of climate change. This gives us the information we need to help various species in appropriate ways.
