The beech leaf-mining weevil was first identified as the insect responsible for foliage damage on American Beech trees in the Halifax area in 2012. I have a photo of damaged leaves on a tree near my house in Waverley from 2011._______________________________________________
There are now very few beech trees still alive here, and the woods have opened up markedly with the loss of so many trees. As far as I can tell, all remaining beech trees are infected.
As long as there are living beech trees in Nova Scotia, I don't think we can say that this has ended.

At Long Lake Prov. Park (Halifax), the majority (>3/4) of Beeches had most leaves eaten away or severely damaged. Some trees were nearly bare. Unaffected trees were mostly isolated from other beeches, typically young, scattered trees.
In a forested area in Cape Breton (Lime Hills), nearly all (>95%) of the beech trees in the forests were dying or dead. Those were beech dominated hardwood forests (other dominant species were yellow birch and sugar maple), and the area was some 1 km from the next road (i.e., spread of the miner was unlikely by people).
I think the leaf miners have been around for at least 5 years. I think to assess the impact, one would have to choose a sample area, and do a bit of counting (# trees in area / # of trees affected / # of trees healthy) and follow for a few years.

Dear All,
Early in 2021 there was concern about a Beech tree leaf miner. Can
someone tell me how that ended.?
In the Kentville area, except for one patch of trees in a location
normally wet year round and entirely dependent upon rainfall but bone
dry when I walked to it,they have fared well.
