Help us to fill the recording gaps across Dorset
We record butterflies over a five year cycle: all the records for this period from all over the UK are brought together and published in the form of an atlas.
We are currently in the first phase of a new cycle, which runs from 2015-2019.
The map below shows the coverage of our recording through the last five-year cycle, from 2010 to 2014. The kilometre squares without any dots in them - the White Holes - are where no butterfly of any species has been recorded (or we haven't been sent the record).
The map shows that we succeeded in recording in 81% of the kilometre squares in Dorset - a fantastic effort. The exact figure was 548 out of 2915.
You can view a version of the map on Google Earth, which is better if you want to see detail.
Please note: The dots on the map are computer generated, but the roads and other markings have been added manually, so don't expect them to be absolutely accurate, but hopefully they will help you orientate yourself.
Please note the butterflies you see and send the records to us however best suits you - the list of possibilities is on our How to Record page.
Filling these White Holes is a great excuse for getting out into the glorious Dorset countryside (or towns) and doing some butterfly spotting.
Pick an area where recording is needed, get out your map to see what roads or footpaths give you access to the area, and go spotting:
