MIMULUS.
Monkeyflowers. [Scrophulariaceae]
|
Five
species of Mimulus are recorded in Britain. All are introduced. The BSBI provide a downloadable plant crib for Mimulus Section Simolus.
Two British miners are recorded on Mimulus.
A key to the European miners recorded on Mimulus is provided in Bladmineerders van Europa.

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Mimulus
|
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 Mimulus, in Britain,. Widespread
throughout Britain. Also recorded in the Republic of Ireland.
Widespread in continental Europe.

Liriomyza strigata (Meigen, 1830) [Diptera: Agromyzidae]. |
1b > 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 in several plant families, but
not yet on Mimulus, in Britain. On numerous
genera and species of several plant families elsewhere, including Mimulus. Widespread in Britain and continental Europe.
Also recorded from the Channel Is.
