I am working on aquatic insects on various aspects. Right now I am concentrating on how climate change impact effects aquatic insects based on ecological preferences and distributional patterns.
Hello Sundar ! Aquatic insect is a very diverse group. Each and every order reflects the surrounding environment or ecology. They are very particular to show their reaction towards the change in ecology sometimes sensitive while sometime tolerant. As per your interest is concerned, I think you should go for study involving functional feeding groups so that you can understand the ecology of the region and get any conclusion over its impact.
I thought that these publications using Species Distribution Models were quite interesting. Is this what you've been looking for?

It strikes me that insect emergence timing would be worth looking at. Accumulated degree days often drives these patterns and should change under climate-change. In some cases there may be long-term data from fishing groups watching the 'hatches'.
In fact the CHironomidae (non-biting midges, Diptera) are from far used for reconstruction of past climate changes during Holocene and last deglaciation. There have been established many models allowing for inference mean summer temperature, mostly in Europe, North America and North Asia. They contain training sets which are lets say, datasets on modern gradients in assemblages composition through the climatic zones and transfer functions which allow to link this information to the fossil samples.
You may find many of such a reconstructions and some models in Stephen Brooks and Angela Self publications from the Natural History Museum in London
