Mines..... Help needed!

It's about this time of year that my attention turns to leaf mines. The majority of species mine leaves between September and October. Generally I compile a list of around 20 species, but even though the garden has changed very little as far as hosts are concerned, the species list varies quite considerable and has never been the same from one year to another. Once again I have added new species to the garden list. The top two images are the newbies and below those are are few that I'm not sure about.........

112 Stigmella luteella  Lyonetia clerkella
 Totally caught out by this. I can't remember seeing the larvae so clearly. The 'Michelin Man' heavily segmented look of the larvae is diagnostic.

260 Leucoptera malifoliella
 NFG- This was found on Conference Pear. Again only one mine found.

Mine on Birch?
 Not sure on this one, very small. Could just be an aborted L. clerkella mine.

99 Stigmella hybnerella
On Hawthorn- very common

Mine on Hawthorn?

Stigmella Sp. on Bramble
To me this looks like Stigmella splendidissimella but after doing a little research it seems that it could be a sub species of S. aurella (f. gei). My question is; can you tell the difference without breeding through?

1 comment:

  1. luteella - no they are Lyonetia clerkella as the larvae of clerkella have a very distinctive bobbly Michelin Man shape like these.
    malifoliella - yes
    no3 unidentifiable
    No4 - Stigmella hybridella
    No5 Not identifiable
    no6 well probably aurella - you would need to breed splendidissimella to prove it.
