A Biodiversity Information System for Cheshire, Halton, Warrington & Wirral

It's worn and partly covered by a blade of grass. Any ideas for what it could be, please?

Hi Dave.

Almost impossible to tell from that angle. Could be a Flounced Rustic I suppose,

Thanks Greg. It was always a long shot! I just wondered if there was anything unusual about it that might strike a chord. I'll note it as "Unknown" with a comment of possible Flounced Rustic.
