Lake Tahoe is a high elevation lake known for its crystal clear water. The clarity allows light to penetrate deep into the water and support plant communities at great depths. These deepwater beds are habitat for mosses, liverworts, multicellular algae and stoneworts. The Tahoe Stonefly, Capnia lacustra, feeds by shredding leaf material from these deep water plants. The Tahoe Stonefly is wingless as an adult and spends its entire life underwater, one of the few stoneflies to do so. The life history makes this insect difficult to study. Populations have been declining due to uncertain factors. Human activity is making the water less clear and a number of non-native species have been introduced.
