Aquatic Entomofauna: Bug
and Beetle Diversity of Hyderabad
Deepa Jaiswal
Abstract
The present work was taken up during 2008-2012, as a part of annual
programmes of Freshwater Biology Regional Centre, Zoological Survey
of India, Hyderabad assigned to the author on “Aquatic insects with spe-
cial reference to Hemiptera and Coleoptera in the different lakes of
Hyderabad, Andhra Pradesh”, in which major lakes were selected, viz.
Wyra, Pocharam, Kolleru, Hussain Sagar, Miralam, Himayat Sagar,
Durgam Cheruvu and Manjeera. The study is signifi cant due to its maiden
effort to study the two orders of entomofauna, Hemiptera and Coleoptera,
in the different lakes of Hyderabad, Andhra Pradesh. Insect collections
were made from various surveys to the different lakes in and around
Hyderabad, during April, 2008, to December, 2012. More than 223 spe-
cies of aquatic Coleoptera and 275 species of Hemiptera known from
India, but only 14 species of Hemiptera belonging to 5 families and 31
aquatic beetle species belonging to fi ve families recorded. The systematic
key for identifi cation is also given to help the young researchers to easily
sort and identify the vast group of entomofauna. More intensive survey
spread over different seasons would be required to provide a complete
picture of the aquatic insect diversity of Hyderabad. Studies aiming to
improve our knowledge on water insects should focus on collecting in lit-
tle known areas, revision of the still unstudied material from additional
families and fi lling the large gaps in our knowledge regarding the diversity
of water insects in some specifi c habitats.
