Afternoon All

Can someone please confirm if this Micro is Eudonia lacustrata.

Thanks
Greg

Looks good to me Greg - but there are others rather better qualified to comment than myself!

]Greg & Julian,

This moth is mercurella for the following reasons. I've included an image off the web (thanks Allan hope you don't mind) as a good example of lacustrata.

In mercurellathe white antemedian line has an extensive dark smudgy border in which the blackish stigmata are not clearly defined.
In lacustrata there is a neater black border distad of the white antemedian line and the four blackish stigmata are clearly visible.

The white postmedian line on mercurella has a narrow black border basad.
The white postmedian line on lacustrata has a stronger, neat black border basad. This black line also forms a neat, tidy border distad to the extensive pale central wing area.

The wing shape at rest is subtlety different, with lacustrata holding them very slightly less tight, making them appear marginally wider.
There are some other features but the above should differentiate the two.

John. ( Can't manage an image at present, hope it follows soon)

Hi John,

Many thanks for the precise identification details of my moth.
