Additionally, according to Mann and Elliot many invertebrates including leeches prey on the larvae and pupae of chironomids. Lumbriculus variegatus and Helobdella elongataare detritivores Edmonson, ; Pennak,Barnes and Edwards have mentioned that Helobdella elongata is also an hematophage species that may df a parasite of vertebrates and invertebrates.

Abundance and first record of benthic macroinvertebrates in Lake Metztitlan, Hidalgo, Mexico. Cephalopods of the world.

So the time it took for the lake to fill up is not the reason for the low abundance, only the number of species increase, in accordance with Margalef who mentioned that the benthic community attains its composition after approximately a year and does not change substantially after that.

The diet was compared between sexes and spatio-temporal variations of the diet were also determined. Organisms belonging to the classes Oligochaeta, Hirudinoidea and Ostracoda were identified with the keys of Edmodson and Pennak, and those of the class Insecta were identified with the keys of PennakPinder and Merritt and Cummins Natural processes and anthropogeneic factors such as disribucion natural silting up of the basins and the construction of an outflow tube drainpipe play a great part in regulating the water level in the lake S.
