Resumo: 	The crustaeeans of Aeglidae family oeeur in South America's fresh water enviranments, featuring as important links in the food chains. The present article has the intention to give an acount of the results from investigations made from April/2000 to July/2001 on the biological and ecological features of Aegla leptodactyla Buckup &amp;amp; Rossi, 1977, an endemic species from the headwaters of the Rio Pelotas Basin in Rio Grande do Sul State, Brazil. The sampling was performed at the Rio da Divisa, tributary of Rio Pelotas, municipal district of São José dos Ausentes, Rio Grande do Sul. The animais were collected with a hand net (puçá) at four different sites of the river. High contents of dissolved oxygen was verified, with a medium value of 108% and alow conductivity (avarage of 13.7mS/cm). The water mean temperature was 16ºC and the pH remained neutral, average of 7.5. The velocity of the water current varied from 0.54 to 0.78m/s. A total of 1,323 males and 1,112 females of A. leptodactyla was sampled. Ovigerous females were observed from April through September and the smallest egg bearing female measured 14.09 mm cephalothorax length. The recruitment took place in November and December. The sex-ratio of the population was 1.19 males for 1 female.
