Leaf mine. ( Figs. 109–110 ) Whitish; initially linear, gradually widening to an irregular, often elongate blotch, in our examples usually not obscuring the linear portion. In some mines, frass is extremely sparse throughout; in others, the linear portion has frass deposited in a line of strips or in irregular particles forming a loose central band. The shape of these mines is consistent with Frick’s (1956) descriptions and illustrations for Calycomyza humeralis , but he stated that the frass is characteristically “deposited in tiny rounded pellets in a row down the center of the long linear portion”, and in lines of pellets in the blotch that allow one to trace “the movements of the larva, which are frequently twisting.” Ellis (2016) , on the other hand, describes a large blotch that often overruns the short linear portion, and states that the larva hardly produces any frass until ready to pupate, at which point it empties its intestine, forming a mass of frass to which the puparium becomes anchored. Puparium. Dark brown; formed within the mine, with the posterior end glued to a lump of frass on the floor. Distribution.
