This species is recorded by Houard from six different 

 Umbels and from three species of Lam.ium. Swanton (870) 

 (ref. Connold) records it also from Hieracium boreale, but 

 this is almost certain to be M. hieracii.

Recorded by Houard from Hieracium boreale, H. imihel- 

 latiim and other species of Hieracium. Apparently the

 by Connold (Swanton, 870).
