Conclusion
An extensive survey has been undertaken during
the year 2008-2009 for faunal collection includ-
ing the aquatic insects. The diversity of collected
aquatic Hemiptera and Coleoptera has been stud-
ied. The study revealed that there is a low diver-
sity of aquatic Hemiptera and Coleoptera exists
at estuarine waterbodies. 8 genera and 11 species
belonging to 6 families of Hemiptera and two
genera and two species belonging to two families
of aquatic Coleoptera are present in the collec-
tion, and some nymphs of Damsel fl ies, Odonata
and Diptera are also present in the collection but
were not identifi ed. All the species are being fi rst
recorded from the study area.
