GALEGA.
Goat's Rue or French Lilac. [Fabaceae]
|
Goat's
Rue or French Lilac (G. officinalis) is the only species
of Galega recorded in Britain. It is introduced.
Five British miners are are recorded on Galega.
A key to the European miners recorded on
Galega is provided in Bladmineerders van Europa. |

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Galega
|
1a > Leaf-miner: A distinctive mine primarily above mid-rib, with irregular short
lateral offshoots into leaf blade. Pupation external (Spencer, 1972:
51 (fig. 172), 55; Spencer, 1976:
270, 271 (fig. 486)).
Branched,
whitish, upper-surface corridor; main axis overlying the midrib;
side branches overlying the main lateral veins. (In Campanula and Phyteuma the mine is much less branched, sometimes nothing
more than a corridor on top of the midrib). Frass in rather long
strings. Usually the mines begins as a long and narrow, shallow,
tortuous lower-surface corridor that ends upon the midrib but otherwise
is not associated with the leaf venation. Often this initial corridor
is filled with callus, and then even less conspicuous. Pupation
outside the mine.
A
linear mine on the upper surface, usually following the midrib and
showing side branches along the veins. The frass is in strings. |
|
Polyphagous. On more than 40 host genera in 15 families, but not yet on Galega, in Britain,. Widespread
throughout Britain. Also recorded in the Republic of Ireland.
Widespread in continental Europe.
|
Liriomyza strigata (Meigen, 1830) [Diptera: Agromyzidae]. |
1a > Leaf-miner: An upper surface linear mine with frass in conspicuous greenish
strips, largely alternating at each side of the channel. Puparium
yellow |
|

Polyphagous. On numerous genera of Fabaceae, including Galega, in Britain
and elsewhere. Widespread in Britain. Also recorded in the Republic
of Ireland and widespread and common throughout most of Europe.
|
Liriomyza
congesta (Becker, 1903) [Diptera: Agromyzidae]. |
1c > Leaf-miner: A short, irregular, linear upper surface mine on any part of the
leaf. Also recorded from young pods (Bland, 1997a).
Long
corridor mine. As a rule the first part of the mine is lower-surface,
the later part upper-surface. Often the loops are so dense that
a secondary blotch is the result. Because upper- and lower-surface
corridor segments often cross, the mine obtains a strange array
of transparant patches. There is no association with the midrib.
Frass in strings and thread fragments. Pupation outside the mine;
exit slit in upper epidermis.
Mine not associated with the veins or midrib of the leaf (It is this character which enables distinction from another Agromyzid pest species - Liriomyza huidobriensis). The larvae may leave one leaf (if not large enough) and enter another leaf, via the petiole). It exits the leaf to pupate through a semi-circular slit in the upper surface of the leaf. |

Polyphagous. On 119 plant genera in 31 plant families of which only 4 plant genera in 2 plant families, but not yet on Galega, in Britain. Local, probably introduced
to Britain. Widespread in continental Europe particularly in Botanical
Gardens and glasshouses. Also recorded in Egypt.
|
Liriomyza bryoniae (Kaltenbach, 1858) [Diptera: Agromyzidae]. |
1d > Leaf-miner: The
first generation initially forms an unmistakable leaf-mine on Anthyllis
vulneraria, but the second generation feeds on the flowers.
Feeding signs on other plants vary in appearance. Larvae can move
between sewn leaves, and more than one larva may be found together.
Larvae in a small full depth blotch, often with extensions. Frass
concentrated in one corner of the mine. The mining activities may
cause the leaf to roll inwards. Older larvae live free among spun
leaves, but still they may make then full depth mines by feeding
on the leaf tissue from a small opening. |

On Anthyllis, Medicago, Onobrychis, Ononis and Trifolium, but not yet on Galega, in Britain and Anthyllis,
Chamaecytisus, Coronilla, Cysisus, Dorycnium, Galega, Glycine,
Hymenocarpos, Lathyrus.
Lotus, Medicago, Melilotus, Onobrychis, Ononis, Ornithopus, Oxytropis, Phaseolus, Psoralea, Trifolium, Trigonella and Vicia elsewhere. Britain including the Channel Is. and Northern Ireland.
Also recorded in the Republic of Ireland. Widespread in continental
Europe. |
Aproaerema
anthyllidella (Hübner,
1813) [Lepidoptera: Gelechiidae] |
1e > Leaf-miner: In the first instar the larva mines the leaves, forming short,
irregular, blotch-like mines, but in later instars it lives externally,
feeding in spun leaves and often twisting those of tender shoots. Larval head light-brown or yellowish brown, edged with black postero-laterally,
ocellar area blackish; prothoracic plate black edged with whitish
anteriorly; abdomen dull dark green; pinacula distinct, black,
sometimes brownish but with black bases to setae; anal plate large,
black (Bradley et al., 1973).
Small,
full depth mine without a definite shape; little frass. Some silk
is deposited in the mine. The larva soon leaves the mine and continues
feeding among spun leaves. |
Polyphagous. On numerous genera and species of plant families, but not yet
on Galega, in Britain. On numerous genera
and species of plant families including Galega elsewhere.
Widespread in Britain and continental Europe. Also recorded from
the Channel Is.
