Leaf mine. (Fig. 80) Narrow and linear throughout; greenish to whitish, with dark green to black frass, typically in alternating strips or closely spaced grains, but in some cases partially forming a squiggly line. Mines are generally confined to the upper leaf surface, but some mines on Mecardonia were partly formed on the lower surface.
Puparium. Yellowish; formed outside the mine.
Phenology and voltinism. This species is multivoltine. We have collected larvae on 7 March in southern California, 26 March in Florida, and 20 May and 2 June in North Carolina, with adults emerging in 12–25 days in each case.
Distribution. Widespread in North, Central, and South America; introduced in the Old World. Largely restrict- ed to greenhouses in colder temperate regions (Lonsdale 2011).
Comments. This is the first record of any agromyzid from Mecardonia Ruiz & Pav.
