...reared from leaf spots on Smilax rotundifolia L. (Smilacaceae) and Uvularia sessilifolia L. (Colchicaceae) in which the solitary larva was clearly visible through the lower epidermis...R. J. Gagné initially identified the specimens from Smilax as belonging to an undescribed species (which he has also reared), but upon further study he was unable to find any morphological differences between specimens from this host and M. aquilonia Gagné... He is, however, reluctant to accept that they are conspecific until molecular data are available (Gagné 1989 and in litt., 18 August 2024).

A number of American Liliaceae have simple leaf spot galls about 8 mm in diameter made by unidentified cecidomyiids for which the adult stage has not been reared. Each spot contains a single larva that leaves the gall when full-grown. At that time the spot becomes translucent and more noticeable...
