About the Image

A hawk moth (Basiothia schenki, Sphingidae) visiting the night-flowering Zaluzianskya natalensis (Scrophulariaceae; upper left) and a long-proboscid fly (Prosoeca ganglbauri, Nemestrinidae) visiting the day-flowering Z. microsiphon (lower right). These two plant species occur sympatrically on Mt. Gilboa, South Africa. Morphological and inter-simple sequence repeat (ISSR) data support the hypothesis that gene flow is occurring between these species despite their apparent ethological isolation.
