Chromatomyia lonicerae
(Robineau-
Desvoidy) (
444
)
syn.
Paraphytomyza lonicerae
Robineau-
Desvoidy
A widely distributed pest of honeysuckle (
Lonicera
) and
snowberry (
Symphoricarpos rivularis
), heavy
infestations sometimes developing on cultivated bushes
in parks and gardens. The mines are relatively small but
distinctly broadened in their later stages. Several are
often present in the same leaf. Unlike the previous
species, there is just one generation annually and
occupied mines occur in the early summer. Adults are
distinguished from those of
Aulagromyza hendeliana
by
the entirely dark knees on the middle and hind legs.

Chromatomyia primulae
(Robineau-

)
syn.
Phytomyza primulae
Robineau-Desvoidy
Leaves of wild primrose (
Primula vulgaris
) and
cultivated species of both
Polyanthus
and
Primula
are
attacked by this common and widespread species. The
larvae form long, silver-white linear mines, in which
widely scattered lumps of black frass are clearly visible.
Pupation occurs within the mine in a whitish puparium.
Adults (wings 2 mm long) have black legs with yellow
knees.

Chromatomyia scolopendri
(Robineau-
Desvoidy) (
446
)
syn.
Phytomyza scolopendri
Robineau-Desvoidy
Associated with ferns, especially common polypody
(
Polypodium vulgare
). Cultivated ferns may be attacked
but damage is limited to the presence of mines and,
therefore, not important. On hart's-tongue fern
(
Asplenium scolopendrium
) the yellowish-green mines
are extremely long, sometimes exceeding 10 cm, and
are very distinctive. Pupation occurs within or outside
the mine. Adults (wings 2.1-2.6 mm long) are black
and yellow.
