Mono Basin and Hot Creek Area

In 1872 Mark Twain wrote that there was a belt of alkali flies an inch deep and 6' wide all around Mono Lake. There are far fewer today, but they still are an important source of food for shore birds - and they don't bother humans. The black band of Alkali Flies at water's edge stands out against the white foam. Another common name for these insects is Brine Flies.
