Liriomyza euphorbiae Martinez, mine initially a linear, narrow serpentine gallery, widening into a more or less extended irregular blotch. Liriomyza eupatorii Kaltenbach, Asteraceae Eupatorium cannabinum, Belgium, prov. Antwerp, Meerhout, Zeeploop, Limbourg, Ham, de Rammelaars, Antwerp, Olen, Limbourg, Meldert, Schurfert, Liriomyza dracunculi Hering, mine Upper-surface, but almost full depth short, tortuous corridor in the tip of a leaf segment.
Liriomyza centaureae Hering, Centaurea jacea, Belgium, prov. Frass in pearl chains or strings. When there is sufficienty space the first part of the corridor is wound in a dense spiral. This strongly reminds the mine of L. Frass, at least partly, in […]. Gerlach mine Initially an upper-surface, narrow corridor of about 3 cm, that abruptly widens into an ill-coloured secondary blotch, which generally incorporates more or less of the corridor.
Secondary feeding lines usually conspicuous. Pupation outside the mine; exit slit in the lower epidermis. Liriomyza amarellae Hering, mine The mine begins in the stem rind, from there enters via the petiole one, sometimes more, leaves, making several excursions in the leaf. In the leaf the corridors may be strongly convoluted, and form a secondary blotch.

Frass in strings, in turns at either side. Liriomyza alyssi Hering, Diptera, Agromyzide mine Upper surface blotch, widening into a blotch, in the end becoming a mine of the stem rind. Chromatomyia succisae Hering, mine Very long, often branched corridor, narrow till very end, for much of its length lower-surface, mostly in the apical part of the leaf. The corridor frequently intersects itself.

Frass in discrete grains. Pupation in the mine, puparium in a pupal chamber. Around the mine the leaf almost always turns violet. Chromatomyia scolopendri Robineau-Desvoidy, Asplenium ruta-muraria, Belgium, prov. Chromatomyia nigra Meigen, Arrhenatherum elatius, Amsterdam detail Hordeum murinum, Diemen: front spiracula penetrate the epidermis mine Whitish, upper-surface, rather narrow corridor with comparatively large frass grains that are laying further apart than their diameter. Pupation within the mine. The front spiracula of the orange-brown puparium penetrate the epidermis.
Kaltenbach, Holcus lanatus, Diemen penetrating front spiracula; right the anchoring of the puparium in the mine seen from above mine Elongated, shallow, upper-surface of lower-surface blotch, not infrequently several in one leaf. Frass in strings or pearl chains. Th bifid front spiracula of the puparium penetrate the epidermis; the rear […].
Chromatomyia luzulae Hering, Diptera, Agromyzidae mine Brownish, elongated, corridor-like blotch, beginning at the lower surface but later becoming upper-surface. Frass in numerous small grains, not more than 2 mm apart. Pupation within the mine, generally near the base of the leaf. The front spiracula of the gold puparium penetrate the epidermis as two tiny […]. Chromatomyia fuscula Zetterstedt, mine Whitish, upper-surface, descending corridor, about halfway the blade.
Frass in distinct black grains that are lying further apart than their diameter. Pupation in the mine; front spiracula penetrate the plant epidermis.
Cerodontha pygmaea Meigen, Broad elongated blotch. Larvae generally communal. The black puaria are individually anchored within the mine with a silken thread attached at their rear end. Distinguishable from C. Cerodontha imbuta Meigen, Diptera, Agromyzidae mine Not described. Deschampsia cespitosa. Possibly also Calamagrostis canescens. Cerodontha bimaculata Meigen, mine Long, rather narrow corridor, upper-surface or interparenchymatous.
The mine changes direction one or two times. Often the corridor ends in the leaf sheath.
Frass in one or two large lumps. Puparium in the lower part of the mine. Hibernation in the pupal state.

Cerodontha fulvipes Meigen, mine The mine starts as a narrow, mostly upper-surface, sometimes lower-surface or interparenchymatous corridor that goes down to the ligula and from there descends into the leaf sheath, generally taking the inside.

Cerodontha pseuderrans Hendel, mine Mine in the leaf apex.
Frass in a few large lumps. Frass in a few large, black lumps. Puparium formed now in, then outside the mine, yellow- to blackish brown. Aulagromyza orphana Hendel, mine The mine begins in a leaf, that soon withers sign to look for, when trying to find this miner. The larva continues living as a miner in the skin of the stem. Puparium in the mine. Frass in the first part of the mine in […]. After the first moult this changes into a large primary blotch without feeding lines. Frass in […]. Ophiomyia pulicaria Meigen, Taraxacum officinale, Nieuwendam detail mine Broad corridor overlying the midrib, with short excursion into the blade, mainly in its basal part.
Frass concentrated in the basal part of the mine, corridors almost free from frass. Pupation in the mine, also in the basal part. Ophiomyia maura Meigen, Solidago virgaurea, Luxemburg, Ahn Palmberg mine Upper-surface, very slender, up to 40 cm long corridor that repeatedly winds through the leaf. Frass in remarkably large, very widely spaced grains. Puparium in the mine, at the end of the corridor. Ophiomyia galii Hering, mine De mine begins as a corridor in a leaf, descends from there as a rind mine; there also the pupation.
Ophiomyia delphinii Hendel, mine Upper-surface, but relatively deep, corridor. The corridor generally begins in the tip of a leaf segment but never at the very margin , descends towards the centre of the leaf, then either switches to another leaf segment, or returns towards the tip of the first segment, all the while broadening considerably. Ophiomyia curvipalpis Zetterstedt, mine Fine, upper- or lower-surface corridor, ending upon a thick vein. From there the mine extends finally to the rind of the stem.
There also the pupation takes place, usually not far from the root collar. Mines in the stem rind often are conspicuous through a red discoloration. Ophiomyia cunctata Hendel, Taraxacum officinale, Nieuwendam Lapsana communis, Rhenen mine The mine begins as a very narrow, upper- or lower-surface corridor, somewhere in the blade.
When this hits a thick vein the larva uses this to descend towards the midrib. From that moment the lave lives in the hollow midrib. From here short, lobate […]. Ophiomyia beckeri Hendel, Lapsana communis, Nieuwendam mine In Asteraceae the larva mostly lives as a borer in the midrib of the leaves. From there short corridors are made into the blade.
Also a corridor can be made overlying the midrib. In Euphorbia a small mine is made in the bracts of the inflorescence. Melanagromyza cunctans Meigen, on Lotus gall slender fusiform swelling of the stem, mostly high in the plant. Inside a white larva maggot or a puparium.
