A morphological description of the last (fifth) instar larva of Macrostemum floridum (Navás 1929), its life cycle, and feeding habits are provided. The study was conducted along the Khlong Yan Stream in Kaengkrung National Park, southern Thailand. Larval identification was achieved by the metamorphotype method of associating immature stages with the adult. A graph of head capsule widths for all instars is provided. Gut content analysis showed that the main food items were diatoms, green algae, and blue-green algae. The larvae construct fixed retreats and feed as collecting filterers.
