Sanitarian (R) United States Public Healtli Service The brackish marshes bordering the Great Salt Lake are proUtic mosquito breeding areas ; they also are the habitat of predaceous tiies which find a plentiful source of food in the mosquito larvae and pupae that become stranded in shallow water and mud during the dry periods of late spring and early summer. Inspections conducted in this area during May and June of 1945 and 1946 afforded the writer several opportunities to observe five species of predaceous flies vvhich were preying on moscjuito larvae and pupae. The observations were made at a time when the marginal areas of the extensive marshland were rapidly drying out. resulting in a heavy concentration of larvae and pupae in the shallow water of nu- merous pools.
