A fascinating community of tiny living things in the thermal basins goes unnoticed by most visitors. Would you expect to find insects living outside in zero degree weather? Look closely at the runoff channels of hot springs and see a lush growth existing in one of the coldest areas in the country. In places green plants grow along the edge of runoff channels, and thick, luxurious mats of algae and bacteria line the bottom. Living in the algae mat and skimming the surface of the water is a community of mites, spiders, and flies, all dependent on one another for survival. The flies not only thrive in Yellowstone's winter but actually begin laying their eggs in mid-January.
