During epithelial morphogenesis in Drosophila, the villous apical cell surface is flattened. Fabrowski et al. show that this flattening depends on a dramatic increase in endocytosis associated with the formation of tubular invaginations, revealing a role for membrane trafficking in morphological remodelling.
