The map of Dorset is divided into kilometre squares. Our aim is to get as many butterfly species recorded in as many squares as possible. You can see what the current situation is by using our interactive map:
We record butterflies nationally over a five-year cycle, e.g. 2020-2024. All those records are then brought together and published in the form of an Atlas.
The map shows:
- All records from all sources for previous complete years in the current five-year period.
- All records reported to the branch website since the beginning of the current year.
You can help
Going out to spot butterflies in under-recorded squares is a great excuse to get out into the glorious Dorset countryside (or towns) and do some butterfly spotting.
