The Lepidopteran proboscis is a prime example for a long, tube‐shaped, siphoning organ that evolved for the uptake of concealed floral nectar. Among lepidopterans, Sphingidae are oustanding models of evolutionary co‐adaptations of insects and flowers, pollination biology, sensory physiology and biophysics of fluid‐feeding. In this issue of the Journal of Morphology, Reinwald and coauthors (pp. 1390‐1410) report about a comparative morphological study of the feeding apparatus of representatives of all high‐rank taxa of Sphingidae. The cover image shows a frontal view of a 3D‐reconstruction of the head of the nectar‐feeding Agius convolvuli , including muscles of the proboscis base and the stipes pump.
