Alkali flies in the Mono Basin (Mono Lake) Article

Alkali flies in the Mono Basin (Mono Lake) - Article Example Alkali flies also known as brine flies or Ephydra hians are a very rare species to find (Eagen 29). This is attributable to the fact that the species breeds well only in certain habitats, especially in alkaline waters. This probably explains why the insect is called the alkali fly. Found in Mono Lake, California, the fly breeds well on the surface, shorelines, as well as beneath the lake. Most of these species of fly are dark brown in color with an adult measuring between 4 to 7 mm long (Carle, and Banta 25). The fly has segmented thorax, which is bluish in color, while the wings are brownish in color. Unlike the ordinary flies, alkali flies normally spend most of their life circles entirely beneath the water surface. This makes the fly unique in addition to the fact that it breeds well in alkaline environment. Mono Lake is one of the most dominant lakes in California. Circular in shape, Mono Lake draws most of its waters from the surrounding streams. However, since the lake has no outlet, the lake is highly alkaline (Eagen 29; Jiang, Steward, Jellison, Chu, Choi 19). This is attributable to the continuous accumulation of salt in the lake. A research conducted more than three decades ago indicated a correlation between the alkalinity of Mono Lake and the availability of alkali flies. According to the research, the alkalinity of Mono Lake provides a suitable breeding ground for alkali flies (Tierney 15). Other researchers have also demonstrated that salinity and alkalinity of Mono Lake has a huge impact on the algae found on the lake. The presence of these algae on the lake also influences the growth and development of alkali-fly. According to Wiens, Patten and Botkin (595), the salinity of the lake makes it difficult for algae to thrive. This leads to a reduction in the number of algae in Mono Lake, thereby compelling larvae to utilize high amount of energy to rummage. This normally leaves very little osmoregualation to take
