Frequently Asked Questions

The Garden Butterfly Survey is a UK citizen science project that anyone can take part in if they have regular access to a private or shared garden (including allotments). Participants share their observations of butterflies in gardens through this website and, when collated together, these data help Butterfly Conservation and others to understand how butterflies are faring in the UK's gardens. Butterfly Conservation run the survey because we'd like to assess the importance of gardens as habitat for butterflies and determine how people can best manage their gardens to help boost butterfly populations. Sightings and information submitted about gardens will help answer these questions. The survey scheme is set up specifically for gardens and you can share sightings from any time of year. This is different from Butterfly Conservation’s other schemes and surveys which focus on other habitats, or take place over only part of the year. Please note: your Garden Butterfly Survey sightings will not form part of the Big Butterfly Count.

We want to know which butterfly species are in your garden and how many of them are present throughout the year. Sign up and tell us a few facts about your garden. Then  throughout the year you can log your sightings through this website. There is no set method, you don’t have to spend a particular length of time looking and you can submit records as often as you wish. However, it is helpful for the results if you check your garden at least monthly in reasonable weather so we get a year-round picture.  When counting, please note the maximum number of each species present in the garden at the time. Butterflies can be very active so try not to count the same individual more than once. You should not enter negative records (i.e. when you have looked for butterflies in your garden but not seen any).

If you previously participated in the survey from our old website (2016-2022) you will need to register again on this new site and create new log in details, your previous log in details will not work.

Thank you for your support and for joining again. Your previously entered records have been shared with data verifiers for Butterfly Conservation's national recording scheme and local datasets.

Note, when you sign up again (and within your Account edit settings) there is an option for requesting your old Garden Butterfly Survey records to be added into your new account. This option will be available until 31st March 2022 and after that date we will transfer data for those who have requested this with a matching email address. Your old records should appear in your new account later in spring 2022.

To enter a sighting, you first need to sign in (or sign up if this is your first visit to the new website).

Next, click the Submit Sightings menu link. A form will open on the screen. Select the date of your sighting and the survey garden name. The grid reference for your survey garden will now appear automatically and the garden butterfly photographs for your survey region will also appear below. You can click on the 'i' symbol for more information and images of a species.

Find the species you want to record. It is likely to be shown among the garden butterfly photographs open on the form. If not, then click on 'Other species' to expand the list until you locate the correct species.

Click in the empty box below the image of the species you saw. Type the maximum number of that species that you saw in the survey garden at any one time that day. The box will turn green. You can also add a photograph by clicking on the camera symbol for a species.

When you've added all the sightings for that date, scroll down to the bottom of the page and press the blue Submit button.

All sorts of gardens can provide a safe home for butterflies, if managed sensitively. As well as private domestic gardens, you can take part in the Garden Butterfly Survey in a shared, communal garden, community garden or at your allotment. When you register your garden you can tell us which type it is.

If you want to record butterflies anywhere else, please join one of our other schemes.

Your butterfly sightings (but not your email) will be immediately accessible to any organisation or registered users of iRecord and they will be able to use them for non-commercial purposes. iRecord also enables your sightings to be seen and checked by butterfly experts associated with the Garden Butterfly Survey and Butterflies for the New Millennium recording scheme, including Butterfly Conservation staff and volunteers (also known as County Recorders). These individuals will additionally have special access to your email address for their role in checking (verifying) your sightings. 

You may be contacted via the email address you provide if there are any queries about your sightings. This vital process of verification means data are checked and, where necessary adjusted, before any records are added to the UK butterfly recording scheme (Butterflies for the New Millennium) database.

Other organisations such as Local Environmental Records Centres, other conservation bodies and scientific researchers may also access the butterfly records from iRecord or from Butterfly Conservation to support their work. County Recorders may include copies of your records within the local datasets they manage. Your records might be published, for example as part of a distribution map and dataset.

Your Garden Butterfly Survey sightings will not be used as part of the Big Butterfly Count as this has a different methodology (requiring a 15 minute count of specific target species during a short period each summer), so please take part in the Big Butterfly Count separately from the Garden Butterfly Survey. 

Further detail of how your personal data and records are processed, stored and shared can be found in the Privacy Notice and Terms of Use.

You enter the location of your garden during registration by clicking on a map or entering a grid reference. You also give a 'site name' such as the nearest town, borough or village. When you view your own records you'll see the accurate location and the site name.

When Butterfly Conservation and iRecord Verifiers view your records they will also see full details, so your butterfly observations can be checked and any feedback can be provided. Butterfly Conservation and iRecord Verifiers can also download Garden Butterfly Survey records with full details to add them to Butterflies for the New Millennium database and local County Recorder databases that they manage and share.

Other users of iRecord or other Garden Butterfly Survey users cannot view or download your records with full location details in the public view. They can see your name and the garden location blurred to the nearest 1Km without a site name.

Your full record details may be shared, including publicly, according to the Privacy Notice and the Terms of Use. Please read these to learn more about how your personal data and butterfly records are processed, stored and shared.

There are several different schemes, locally and nationally, to record butterflies. We don't want you to enter your garden butterfly sightings more than once. Not only is this extra effort for you but it also creates duplicate records. So, if you take part in the Garden Butterfly Survey you do not need to put the same sightings into other recording systems. Your Garden Butterfly Survey records will be passed on to Butterfly Conservation's local branches and County Recorders, and made accessible to Local Environmental Records Centres.  Our advice is to choose one scheme for your garden sightings.

An exception is the Big Butterfly Count – you may want to take part in this annual snapshot survey from within your garden. Please do, but don’t enter the same count into the Garden Butterfly Survey as well. Or alternatively you could take part in the Big Butterfly Count from other locations.

If you previously participated in the Garden Butterfly Survey from our old website (2016-2022) you will need to register again on this new site, thank you for your support and for joining again. Note, when you sign up (and within your Account edit settings) there is an option for requesting your old Garden Butterfly Survey records to be added into your new account. This option will be available until 31st March 2022 and after that date we will transfer data for those who have requested this with a matching email address. Your old records should appear in your new account later in spring 2022.

Butterflies are relatively easy to identify compared to many other types of wildlife, but can still prove a challenge, especially if they are very active and if you are new to butterfly recording.

If you are not completely sure of the identity of a butterfly that you see in the garden it is best not to enter the sighting. If in doubt, leave it out!

To help with identification, from the Submit sightings page you can click the 'i' symbol on any species to see more information and photographs of that butterfly. Or you may wish to borrow or buy an identification guidebook to take out into the garden with you. When your records are checked by skilled volunteers via iRecord, you may receive feedback on the identification that could help improve your knowledge and future recording.

If the butterfly is not listed in any of the forms on the 'submit sightings' page then you cannot record it directly. If you are certain of your identification then you can include details in the notes section of the sightings form.

If you have signed up again to the new 2022 website you will only see records from this year (or testing records if you are in test mode). However we can arrange for your historic records from the old site to be uploaded into your new account. (Note that these records have already been shared with County Recorders for entry into local and national databases.)

There is an option to request that your old records are added to your new account on the 'Sign Up' form (or via 'My Account' and 'edit' from the website footer, once registered). This option will be available until 31st March 2022. After that date we will manually process the requests; your older records should appear in your new account during spring 2022.

If you used the old site and you would like to request this before 31st March 2022, please register with the same email as you used for the old website and tick the data transfer request check box near the end of the Sign Up page. Or, you can find this option after registering from the 'My Account' link in the website footer and then clicking 'edit'. Note you will need to 'Save' changes to any account edits.

In 2022, Butterfly Conservation relaunched Garden Butterfly Survey with a brand new website. The new site is improving data flow and has been designed with recorder feedback in mind.

Behind the scenes, the new system now feeds directly into iRecord This means your butterfly sightings are now immediately available to County Recorder data verifiers, Butterfly Conservation Branches and Local Environmental Records Centres.

The new website hosts the same year-round garden survey with enhanced recording options. This includes adding photographs to your records, adding more than one garden to your account and taking part from shared gardens, community gardens or allotments.

Throughout the year we will be adding more guidance and resources to the site. And, if you opt in, you can now receive news and advice about gardens and butterflies to your inbox.

This work is part of Supporting Science, a project that’s improving data flow and supporting our recorders and volunteers to access natural heritage digitally. Supporting Science received DCMS and National Lottery funding, distributed by The Heritage Fund as part of their Digital Skills for Heritage initiative.
