Seen berberis sawfly? We would like to know.
As part of our research the RHS would like to know where berberis sawfly has been seen.
Please submit your records via our berberis sawfly survey (expected time to complete survey = two minutes).
Submissions to our pest and disease surveys are stored permanently in an anonymised form in order to monitor the spread of the pest or disease. We may contact you within 2 months of your submission in order to verify your sighting but your personal data will not be permanently stored in connection with your submission and will be deleted after 1 year. We publish and share only non-identifiable data from survey submissions (such as a six figure grid reference) with third parties and the public for the purposes of scientific research and advancing understanding among gardeners.
Thank you to everyone who has submitted records so far – read a blog about the surveys
