Tephritidae is the generic name of the larger of the 2 species of fruit fly.
As you can see his stripes make him look more like a wasp, and that sees off predators.
These sorts of fly will be difficult to spot now as winter is near and they will be dying off.
The small butterfly you see on your left is a "Comma" genus Polygonia, they have elaborate shaped wings.
All butterflies left alive will seek shelter in old buildings or dense cover and emerge next year, albeit temporarily.
The tiny scales that make the wings up do not fare well overwinter and those insects that do survive will look very tatty, not like the one here
The seedhead of a clematis in a hedgerow against a blue sky makes a fantasic picture, even simple things make you wonder at their beauty when you see them close up.
Skeletal cow parsley that has been festooned with webs by spiders makes a show of elegance when the heavy mists coat the cobwebs
To your right is our largest Blue Atlantic Cedar(Cedrus Atlantica Glauca) in full flower at the top end of the park, its a right stunner, I think you will agree.
It is one of those trees that doesn't appreciate waterlogged soil.
