Make a record

We welcome records of the horse-chestnut leaf-miner. We are also interested to know where the horse-chestnut leaf-miner is absent because this gives greater confidence in understanding the changing distribution of the moth. 

Records can be submitted via this website, but records of the leaf-miner can also be submitted via the LeafWatch app, available for Apple via iTunes and Andriod via Google Play.

All records are verfied and used in research about the spread of the horse-chestnut leaf-miner and its impact on horse-chestnut trees.

Submit a record on the website.

Download the app: iTunes (for iPhone and iPad) or Google Play (for Android smartphones)

We have provided a map of the distribution of confirmed records, although note that this requires updating.
