Campanula, bellflower, bats-in-the-belfry, harebell

Incl. Symhpyandra.

Several more stem miners occur on Campanula, that are not treated here. It cannot be excluded that other Ophiomyia‘s now and then may behave similarly.

1a mine full depth; larva with chitinised head => 2

1b mine upper- or lower-surface; larva a maggot => 5

1c galls, etc => 100

2a mine very small; older larvae live free among spun leaves => 3

2b mine of normal size; older larve either in a leaf roll, or mining all its life => 4

3a pinacula colourless (but the bases of the setae are black): Cnephasia incertana

3b pinacula black: Cnephasia asseclana

4a elongated blotch; only in spring, on Campanula persicifolia: Orophia ferrugella

4b mine, at least its first part, a definite corridor: Orthochaetes insignis

5a narrow corridor, descending to the petiole, then to the bark of the stem: Ophiomyia eucodonus**

5b mine larger, not leaving the lea => 6

6a pupation in the mine in a, usually lower-surface, pupal chambe: Chromatomyia horticola

6b pupation outside the mine => 7

7a branching corridor, positioned over the midrib and the more heavy lateral veins: Liriomyza strigata

7b no association with the leaf venation => 8

8a upper surface blotch, preceded by a short, narrow corridor; larvae usually communal: Amauromyza gyrans

8b corridor; larva solitary => 9

9a corridor shallow, whitish; frass in discrete grains: Phytomyza campanulae

9b corridor deeper, greenish; frass in the first section of the mine in pearl chains: Phytomyza rapunculi

100a Nematoda => 101

100b Acari => 102
