2a the lobes used to enlarge the case are cut from the leave’s upper epidermis: Coleophora violacea
2b the lobes are cut from the lower epidermis: Coleophora ahenella
3a elongated blotch on top of the midrib; at either side a large number of lateral corridors emerge: Chromatomyia alpigenae
3b mine different, not associated with the midrib => 4
4a blotch or tentiform mine => 5
4b corridor, in the end widening into a blotch; larva with chitinised head; pupa in a globular cocoon within the mine: Rhynchaenus xylostei
4c corridor mine => 11
5a tentiform mine => 6
5b blotch not or only a little contracted or puckered => 7
6a the (quite large) mine causes the leaf to fold lengthwise: Phyllonorycter emberizaepenella
6b mine smaller, causing the leaf to fold transversely, or into a pepper box: Phyllonorycter trifasciella
7a mine small, irregular in shape, containing only a little frass; older larvae live free among spun leaves: Cnephasia incertana
7b mine larger, more regular; larva mines all its life => 8
8a larva a maggot; on L. biflora: Aulagromyza antlantidis
8b larva with thoracic feet and a chitinised head; on other Lonicera species => 9
9a mine begins at an oval egg shell => 10
9b mine begins at a round hole, through which the larva has entered the leaf: Alucita hexadactyla & Pterotopteryx dodecadactyla
10a larva leaden: Perittia obscurepunctella
10b larva reddish brown: Perittia herrichiella
10b larva whitish with red markins on the thorax: Perittia weberella
11a slender full depth corridor with a central frass line, starting at an egg shell: Stigmella lonicerarum
11b corridor and frass different; never an egg shell visible => 12
12a larva leaves the mine before pupation; corridor never star-shaped, never with a lower-surface initial part => 13
12b puparium within the mine; corridor often stellate and with a lower-surface beginning => 16
13a on L. caerulea: Chromatomyia isicae
13b on L. alpigena: Aulagromyza fallax
13b on other Lonicera species => 14
14a larva in early spring (April, rarely May) in the tender leaf; rear spiraculum with a spine, surrounded by a circle of papilla: Aulagromyza cornigera
14b larvae later in the year; rear spiraculum without a spine => 15
15a frass in discrete granules: Aulagromyza hendeliana
15b frass in a broad green band, with sscattered small black grains: Aulagromyza luteoscutellata
16a on L. alpigena: Chromatomyia nervi
16b on other Lonicera species => 17
17a mine seems to consist of a number of isolated branches, independently arising from the midrib; puparium greenish: Chromatomyia aprilina
17b mine made up of several corridors, diverging from one point (not on the midrib) => 18
18a puparium green; mines in winter and early spring: winter generation of Chromatomyia aprilina
18b puparium light or dark brown; mines in summer and autumn => 19
19a corridor segments relatively long, yellow-green; puparium dark brown; frass in pearl chain: Chromatomyia lonicerae
19b corridor segments much shorter, suggesting a stellate blotch; mine greyish; puparium light brown; frass in discrete grains: Chromatomyia periclymeni
Marquardt (1985a) discusses the biology and ecology of the Diptera miners on Honeysuckle.
Not included in the key: Aulagromyza flavoscutellata (unsufficiently known).
