Mission: alien moth survey
Survey trees in your area - anywhere in the UK - for invading alien moths
What are you looking for? The damage caused by the leaf-mining moth is often obvious, but it can be confused with other types of damage (see the photo below).
This mission ran from 2010 to 2013. We are currently setting up a new way of recording, which we will link to from this website site.
In 2011 we also produced a smartphone app (the LeafWatch app), although from 2014 onwards we can only offer very limited support for this app. It was one of the first apps of its kind (so now would need ot be updated to work efficiently), but we are keeping it on the App Store and Google Play for people's reference.

Check out the identification of the alien moth damage. The damage labelled as 'not a leaf miner' is actually a fungus (called Guignardia) that was introduced by accident, but does not seem to do the trees any harm. It is most prevalent in autumn.
