Please see #1 for the main description of the walk.
The Small Heath is an inconspicuous butterfly that flies only in sunshine and rarely settles more than a metre above the ground. Its wings are always kept closed when at rest, where the eye spot on the underside of the forewing is usually visible, acting as a decoy to any predator.
