heavily infested leaves shrivel and turn brown,
weakening host plants and sometimes causing their
death. Although infestations on greenhouse-grown
plants are often severe, attacks in the open are usually of
little or no consequence.

The characteristic mines of this widely distributed
species occur on honeysuckle (
Lonicera
), causing
considerable disfigurement of affected leaves. Each
mine commences as a stellate gallery but later becomes
distinctly linear, with frass deposited in black lines.
Infestations are noted most often on wild plants but also
occur on cultivated bushes.

larva
a chrysanthemum leaf miner
A widely distributed and generally common leaf miner.
Adults are similar in appearance to those of
Chromatomyia syngenesiae
. The larvae are very
polyphagous, forming galleries in the leaves of various
ornamentals, including
Chrysanthemum
,
Petunia
,
Phlox
, poppy (
Papaver
), sweet pea (
Lathyrus
odoratus
), tobacco plant (
Nicotiana
) and wallflower
(
Cheiranthus cheiri
). In common with
Chromatomyia
syngenesiae
pupation takes place at the end of the larval
mine, but the puparium protrudes through the epidermis
immediately adjacent to the gallery.
