Cornaceae : Cornus canadensis L., C. * drummondii C. A . Mey. , C. sericea L. ( Spencer 1969 , 1981 ); we have also seen leaf mines on C. alternifolia L. f., C. amomum Mill. , C. nuttallii Audubon ex Torr. & A . Gray , and C. racemosa Lam. Leaf mine. Long, narrow, entirely linear, on the upper leaf surface; whitish, with frass in alternating black strips, often with a broad, green central band that occupies nearly the full width and may obscure the frass pattern. Puparium. Yellowish-brown; normally on the ground, but not infrequently remaining in the exit slit at the end of the mine ( Spencer 1981 ). In the Oklahoma example, the puparium was formed entirely within the mine. Distribution. USA : CA, *OK, WA; Canada : AB (larvae only), QC; Europe. We have also seen leaf mines (including photographs posted to www.BugGuide.net) in USA : AK, CO, IA, ID, MA, KS, NH, OR, VT, WI; Canada : NB, ON, SK.
