The wood is home to some unusual species of insect, including uncommon hoverflies and beetles. There is an extraordinary array of fungi in the ancient woodland parts, some with evocative names such as Old Man of The Woods, Chicken of the Woods and Deathcap.

Being rich in fungi, Angling Spring Wood is home to the pleasantly named ‘slender slug’, a nationally designated species of conservation concern. This is a rather attractive specimen – golden yellow with violet horns! An indicator species of ancient woodland, it feeds on toadstools.
