I am about starting a side research project about dragonflies and damselflies. So far, I collect a handful of references for my project and they collectively say that these Odonatans are the indicators for the good quality of (aquatic) environment which is their main habitat. So, out of my curiosity, is there any chance that these insects live in not-so-good aquatic habitat e.g. heavy-polluted water body or degraded pond or else?
If you know any paper discuss about it, it will be great thing...
Thanks in advance
