Please use this form to send us your sightings. We will use the information to share your sightings with others via our website, and it will also be forwarded to our Records Officer to help monitor Dorset's butterfly population. It will be helpful if you can include a Six-figure Grid Reference, in the format XY123456, to ensure the correct site is recorded. Your telephone number and e-mail address details are of course optional, but it would help us to be able to contact you, in case we needed to follow up a sighting. Your help in sending us this information is very much appreciated.
