This study is about the biodiversity of rove beetles. These act as predators, parasites and scavengers. These are also bio-indicators. As far climate of Punjab, Pakistan is concerned, it is a blend of different parameters. So, here should be a plenty of rove beetles but due to less attention this fauna was ignored. During this study, we collected specimens from different cropped and forest areas with the help of 5 different collecting methods. As these beetles live in moist areas, so relative humidity plays an important role in their abundance. the population of rove beetles has positive co-relation with soil moisture contents also. these are also medically important as some species cause Paederus dermatitis. This is a skin irritation. To avoid this, we have to aware about its habitat. This study is composed of many parameters and is very informative.
