Blow flies on Stapelia grandiflora flower

Blow flies pollinating a Stapelia grandiflora flower (from Calitzdorp Dam, Little Karoo, Western Cape, South Africa).

The flies are being tricked by the flower, and their maggot eggs won’t survive as the flower will die soon (and the flower is not really a suitable host or food for the maggots).
