Tonight I found a vacated mine of the ubiquitous Stigmella aurella on a small invasive bramble in the garden. I've had a go at scanning the mine, and using my hardly-ever used USB microscope to check for the egg at the start of the mine (which is necessary for some species I believe). Not convinced the results are good enough but maybe worth trying a few more ......
Stigmella aurella - vacated mine on Bramble.
Long gallery mine, frass dispersed throughout the mine but not in a neat narrow line.
Egg (I think) at the start of the mine on the upper surface.
Badly snapped egg at stupid magnification.
