Rediscovery of the threatened Stoffberg Widow butterfly, Dingana fraterna : the value of citizen scientists for African conservationAbstract The Stoffberg Widow, Dingana fraterna (Lepidoptera: Satyrinae), was only known from a single highly localised population near Stoffberg, South Africa. This butterfly is univoltine, with historical records indicating that adults fly for approximately 10 days in early October. It was last seen in 2002 and was Red-Listed as Critically Endangered (Possibly Extinct). The cause of the extirpation of the type population was inappropriate burning of its habitat during the adult flight period. A new colony was recently discovered in October 2014 at a site 46 km N of the type locality by citizen scientists from the Lepidopterists’ Society of Africa. This study clearly highlights that developing countries, which are often limited in resources, can benefit hugely from the contributions of citizen scientists to conservation initiatives.

a very similar case occured recently also with another RSA butterfkly, the lycaenid Erikssonia edgei (the only original population extinct and recently another new colony discovered). Unfortunelty other cases seems définitive because of man pressure and necessety to occupy more and more lands. In RSA, there are many species very localised and known by only one or a very few localities.
