Biotic Indices of Stream Macroinvertebrates for Fun and (Educational) Profit
Water quality monitoring activities can support student inquiry into ecological concepts and pollution issues, as well as offer insight into integrating field and lab work. This exercise provides students with practice in identification (to order or family level) of stream macroinvertebrates that they've previously collected. Provided information indicates water pollution tolerance of the various taxa. Students use the data to calculate several different biotic indices for the macroinvertebrates

One reason why mites are considered to be arachnids is because they don't have wings and they cannot fly. Mites are so tiny that most of them have to be viewed under a microscope to be seen.
