Mill Hill Nature Reserve is an unimproved chalk grassland since 1937 (and almost certainly before this) of nearly 35 acres – it is a great area for photographing butterflies. Shoreham Bank (Mill Hill) is the most nationally famous of the Sussex butterfly sites. This fame was created by the huge numbers and aberrations of the Chalkhill Blue Butterflies. The fame started from about 1820 when butterfly collecting became the vogue. During the heyday of butterfly collecting between the two World Wars, the site was even kept a secret by commercial collectors.

Altogether at least 30 species of butterflies have been positively been identified at this beautiful location the expectation is for this total to increase. In season the Chalkhill Blue still remains the most prevalent butterfly, with small population of Adonis Blues and Dingy Skippers, mostly on the lower short ward (20 mm to 35 mm) herbland. Large numbers of Common Blues and Marbled Whites are to be found on the upper slopes and these will most likely to be seen by casual visitors, although the dispersals of Chalkhill Blues will venture over the whole area in the search for nectar plants.
