|Looking West from Marshes Hill|
Marshes Hill is an isolated 6ha piece of heathland near Knypersley Pool. The main plants covering the heath are Gorse, Bilberry and Heather. Heathland was once extensive in this part of Staffordshire but now only a few isolated remnants remain. The tiny dots visible in the sky over the gorse are now dust spots, they are St Mark's Flies Bibio marci. This shiny black fly hangs lazily in the air, its legs dangling, in the weeks around St Mark's Day (25th April), hence its name.
