As the mines can be quite numerous on each leaf and tend to be quite large too, they can still be located in fallen leaves or are also still visible on leaves that are still clinging on to the tree.

Early stages: Phyllonorycter platani
This is the most numerous species I have recorded this year, all as leaf mines and all in urban situations up and down the country, including Leeds, Norwich and all around Canterbury.

Early stage excesses
To say that the last few weeks have been productive in terms of early stage finds - mainly leaf miners but also cases and galls - would be an understatement.
Whilst we all seem to have suffered a dearth of adults to the traps this year, with tales of crashes in numbers of usually abundant species becoming clear as we all start to analyse the 2012 figures in detail, here in East Kent I am falling over early stages at every turn.
By way of illustration, here are some figures from the last 15 days i.e. October so far:
213 out of 320 total records (66%) are for early stages
4907 out of 5160 total individuals(95%) are for early stages
75 species recorded as early stages
The most abundant early stages are:
Phyllonorycter coryli - 1126 mines
P. platani- 1505 mines
P. corylifoliella - 355 mines
Other finds include Phyllocnistis xenia, Stigmella aceris, Bucculatrix thoracella, Phyllonorycter platanoidella, Coleophora laricella, Ectoedemia heringella, Parornix fagivora, Strophedra weirana
Phyllocnistis xenia
Stigmella aceris
Parornix devoniella
Stigmella microtheriella
