Resumo: | The diet of the four larval instars of a Chaoboridae species of Lake Monte Alegre, was evaluated through the analysis of the crop content of individuals caught at night in the lake. Peridinium and zooflagellates were the major components of the diet of instars I and II, whereas microcrustaceans, especially the cladoceran Bosmina, were most important for late instars. When the preferential prey decreased, in the course of the year, the diet was more diversified, increasing the ingestion of Peridinium by instars III and IV. There is a relationship between the mouth diameter of the larvae and the maximum width, height, or diameter of the ingested organisms. |
