Mosley (' The Naturalist,' Nov., 1892, p. 338) records this species 

 from Whitley Woods, Yorkshire. He describes the galls as of the size 

 of a large pea, in axils of the leaves, covered with bristly projections, 

 each with a red papilla at the end. Mayr describes it as being usually 

 of the size of a cherry, but may reach the size of a walnut. In size it 

 is spherical, in colour pale yellow ; the bristles are stiff, fibrous, or 

 stalky, standing out radially. It is polythalamous, hard, the cells 

 without an inner gall. 



Hartig describes the insects as fuscous-black ; the tegulae, venter, 

 and feet fuscous-red ; the femora on the outer side, the posterior tibiae 

 and tarsi black. 



Mayr says the third abdominal segment is very distinctly finely 

 punctured, the abdomen castaneous-brown, black above. 



Length 2-8—3-8 mm. 



The flies appear from March to May. There is only one brood 

 known. 



Synergus melanopus and Ceroptres arator are inquilines.
