AN illustrated talk on the natural history of Mill Hill will be held on Wednesday evening (April 10).
Andy Horton will present his talk, assisted with a computer presentation, on the Wednesday evening meeting of the Southern Counties Orchid Society at Lancing Impulse Leisure Centre, in Lancing Manor, at 7:30 pm.
Mill Hill is considered nationally important because of its population of chalkhill blue butterflies, which have been the subject of interest by butterfly collectors since 1826.
The chalk downs nature reserve, north of Old Shoreham Road, is one of the few remaining fragments of original chalk downs that provide a habitat for at least 33 species of butterflies, which can be seen at various times during the warmer weather.
The talk will explain about the history of this small part of the downs and the chalkhill flora which is essential for the survival of the butterflies.
There will be opportunities to ask questions.
The Southern Counties Orchid Society welcomes guest members, with a small admission charge, in the spacious ground floor suite at the Impulse Leisure Centre.
The Southern Counties Orchid Society exists to encourage the cultivation and knowledge of orchids.
The talk will also feature an extra piece about the native orchids found on the local downs.
