SUMMARY1 The synonymy and distribution of the chrysanthemum leaf‐miner are discussed. 2 The host plants are enumerated, and it is shown that the attacks on chrysanthemums decrease by August, although the flies are still common on other Compositae. 3 A description and comparison of the morphology of the three larval instars is given, and the method of feeding of the larva is discussed. 4 The puparium and emergence of the adult fly are also described, together with an attempt to separate the puparia into sexes by measurement. 5 Some degree of natural control is secured by the parasitism of a braconid on which a chalcid is probably hyperparasitic. 6 A table is included comparing the developmental period of Phytomyza atricornis Mg. and P. chrysanthemi Kowarz.
