Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Phyteuma
|
1a > Stem miner: An external stem mine with frass in two rows of disconnected strips.
Pupation in stem at end of mine (Spencer, 1972b: 25; Spencer, 1976:
61 (fig. 63B), 65-6). |
Polyphagous. On Campanula, Jasione, Phyteuma [Campanulaceae], Crepis, Hypochaeris and Lapsana [Asteraceae]
in Britain and additional genera of both families elsewhere. Uncommon
in Britain - recorded in London, Warwick and Cambridge. Uncommon
but Widespread in continental Europe.

Ophiomyia
heringi Stary, 1930 [Diptera: Agromyzidae]. |
1b > Leaf-miner |
2 |
2a > 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 in Britain including Campanula, but not yet on Phyteuma, Widespread
throughout Britain. Also recorded in the Republic of Ireland.
Widespread in continental Europe.
|
Liriomyza strigata (Meigen, 1830) [Diptera: Agromyzidae]. |
2b > Leaf-miner: Mine not primarily above mid-rib. |
3 |
3a > Leaf-miner: A shallow whitish linear-blotch mine. Puparium yellowish brown;
outside the mine |
|
On Campanula glomerata and Campanula rotundifolia, but not yet on Phyteuma, in
Britain. In addition on other genera and species of Campanulaceae
elsewhere. Recorded in England. Also recorded in the Republic
of Ireland. Widespread in continental Europe. Also recorded in
Japan.
|
Amauromyza
gyrans (Fallén, 1823) [Diptera: Agromyzidae]. |
3b > Leaf-miner: An
irregular whitish linear mine which can broaden at end and become
blotch-like (Spencer, 1976:
397). |
On Campanula glomerata, Campanula rotundifolia and Campanula
trachelium, but not yet on Phyteuma, in Britain. In addition on other species of Campanulaceae
elsewhere.
|
Phytomyza
campanulae Hendel, 1920 [Diptera: Agromyzidae]. |
3c > Leaf-miner: Very long, rather deep corridor, initially lower-surface, later
upper-surface. In smaller leaves almost always a secondary blotch
originates, that can occupy the entire leaf. Frass initially in
pearl strings, later in scattered aggregations. Pupation outside
the mine; exit slit in upper epidermis. |
Hosts in Britain unknown. On Campanula and Phyteuma elsewhere. Added to the British checklist
by Henshaw in Chandler, 1998. Widespread in continental Europe.
