Observations and life-history. — As previously mentioned 

 (Vol. III., p. 247, 1903) this species is essentially a salt marsh 

 insect. It, however, is capable of flying inland some distance, 

 this migratory habit supplying mosquitoes to districts where none 

 may breed. 



It winters in the egg stage in the soft mud of the salt 

 marshes.
