This species ranges over practically the whole of the United 

 States. The larvae favor permanent swamps and pools in more 

 or less wooded areas. In the west the species becomes re- 

 stricted to mountainous or forested areas, avoiding the open 

 plains. The larvae have a long tube somewhat expanded at 

 the tip. The male genitalia are distinctive, the unci having 

 lost the second or toothed plate. The adult does not bite warm- 

 blooded animals, but has been observed attacking frogs.
