Northeastern and central United States, ranging from Maine to 
Virginia, west to Arkansas. 
At "The Rocks" wharf on the James River, Virginia, while a 
member of the second trip of the ''Ecphora, " under Prof. Gilbert D. 
Harris, of Cornell University, in quest of Tertiary fossils, I found this 
species in large numbers resting on the dripping, water-spattered 
•cliffs of the Yorktown (upper Miocene) formations. On July 2, 
1915, they occurred in large numbers, together with Dicranomyia 
'hadia Walker. Many were found to be heavily infested with a 
species of Tromhidium, while others, in large numbers, were found 
beaten into the mud by being struck by the heavy particles of water 
dripping from above. 
In the north {Ithaca, New York) they occur in mid-summer 
(August) on rich vegetation along streams. The adult flies feed on 
various Composite flowers {Solidago, Erigeron) and also on Daucus 
(Umbellif erse) .
