The Prosoeca peringueyi (Diptera: Nemestrinidae) pollination guild in southern Africa: long-tongued flies and their tubular flowers Abstract | Materials and Methods | Results | Discussion | Literature Table 4 Pollinator characteristics and effective tube length of species with the Lapeirousia silenoides-type flower. Measurements of insect mouthparts were made from individuals collected on the plant species concerned. Dash in column three reflects no pollinator recorded on that species.
