The fourth instar larva and pupa of Bezzia roldani is described and illustrated by using a phase-contrast stereoscope and Scanning Electron Microscope. Immatures were collected by placing floating hydrophytes of the genera Lemna, Wolffia, Wolfiella and Spirodella in Berlesse funnels. The hydrophytes were collected in the Chascomús and Los Talas ponds, both in the province of Buenos Aires, Argentina. The larva has character states typical of carnivorous larvae, and it is compared with the one of B. nobilis and with a similar species of the genus Palpomyia Meigen, P. guarani. The pupa is compared with its similar congener B. blantoni.
